Nathan plays amateur baseball. He played for 3 hours for two weeks, every day. His friend Tobias played for 5 hours every day, but only for one week. How many hours did Nathan and Tobias play in total?

How many hours did Nathan play? ** Two weeks are 14 days, so Nathan played for 3 * 14 =

<<14*3=42>>42 hours. How many hours did Tobias play? ** Tobias played for 7 days, so he played a total of 5 * 7 = <<5*7=35>>35 hours. How many hours did Nathan and Tobias play in total? ** Nathan and Tobias played together for 42 + 35 = <<42+35=77>>77 hours. #### 77 A piece of wire 5 feet 4 inches long was divided into 4 equal parts. How long was each part in inches if 1 foot is equal to 12 inches? How many inches are in 5 feet? ** Five feet is equal to 5 feet x 12 inches/foot = <<5*12=60>>60 inches. How long was the wire? ** So, the total length of the wire was 60 inches + 4 inches = <<60+4=64>>64 inches. How long was each part? ** Hence, each part is 64 inches / 4 parts = <<64/4=16>>16 inches/part. #### 16 Rob has 24 baseball cards, and a few are doubles. One third of Rob's cards are doubles, and Jess has 5 times as many doubles as Rob. How many doubles baseball cards does Jess have? How many doubles baseball cards does Rob have? ** Rob has 24/3=<<24/3=8>>8 doubles baseball cards. How many doubles baseball cards does Jess have? ** Jess has 8*5=<<8*5=40>>40 doubles baseball cards. #### 40 Alexander is going food shopping. If he buys 5 apples for $1 each and 2 oranges for $2 each, how much does he spend? How much does Alexander spend on apples? ** Alexander spends 5 * $1 = $<<5*1=5>>5 on apples. How much does Alexander spend on oranges? ** He spends 2 * $2 = $<<2*2=4>>4 on oranges. How much does Alexander spend in total? ** In total, he spends $5 + $4 = $<<5+4=9>>9. #### 9 A wild tiger escapes the zoo. He escapes at 1 AM and zookeepers do not notice he is missing until 4 AM. He runs at a speed of 25 mph. It takes 2 more hours to find him but after 4 hours of running, the tiger slows his speed to 10 mph. He then gets chased for half an hour going 50 mph. How far away from the zoo was he caught? How many hours was the tiger running? ** He was running for 4-1=<<4-1=3>>3 hours How many miles did the tiger run? ** So in that time he runs 3*25=<<3*25=75>>75 miles How many hours did the tiger run at 25 mph? ** Since he slowed down after 4 hours, the time he spent running at 25mph was an additional 4-3=<<4-3=1>>1 hours How many miles did the tiger run in the first hour? ** So in the first hour they were finding him, he ran 1*25=<<1*25=25>>25 miles How many miles did the tiger run in the second hour? ** In the second hour they were finding him, he ran 1*10=<<1*10=10>>10 miles How many miles did the tiger run during the chase? ** Finally, during the chase, he ran 50*.5=<<50*.5=25>>25 miles How far away from the zoo was he caught? ** So he is 75+25+10+25=<<75+25+10+25=135>>135 miles away #### 135 One-third of a class of 39 students took part in a math competition. How many students did not participate in the competition? How many students participated in the competition? ** Since one-third of the class participated, there are 39 * 1/3 = <<39*1/3=13>>13 students who participated in the competition. How many students did not participate? ** This means that 39 – 13 = <<39-13=26>>26 students did not participate. #### 26 Five times a week, Onur bikes 250 kilometers a day. His friend Hanil bikes 40 more kilometers of Onur biking distance in a day. What's the total distance the two friends bikes in a week? How many kilometers does Onur bike in a week? ** Since Onur bikes 250 kilometers in a day, he bikes 5*250 = <<250*5=1250>>1250 kilometers for five days in a week. How many kilometers does Hanil bike in a day? ** Onur's friend Hanil bikes 40 more kilometers in a day than Onur, meaning he bikes for 250+40 = <<250+40=290>>290 kilometers. How many kilometers does Hanil bike in a week? ** In five days of the week, Hanil covers 290*5 = <<290*5=1450>>1450 kilometers. How many kilometers does the two friends bike in a week? ** In total, the two bikes for 1450+1250 = <<1450+1250=2700>>2700 kilometers in 5 days of a week. #### 2700 Tommy has 3 toy cars. His neighbor, Jessie, has 3 cars too. Jessie's older brother has 5 more cars than Tommy and Jessie. How many cars do the three of them have altogether? How many cars do Tommy and Jessie have together? ** Tommy and Jessie have 3 + 3 = <<3+3=6>>6 cars. How many cars does Jessie's brother have? ** Jessie's brother has 5 + 6 = <<5+6=11>>11 cars. How many cars do Tommy, Jessie, and Jessie's brother have altogether? ** Altogether, they have 6 + 11 = <<6+11=17>>17 cars. #### 17 Lily types 15 words a minute and takes a 2-minute break every 10 minutes. How long does it take for Lily to type 255 words? How many minutes would it take Lily to type 255 words without taking a break? ** It would take Lily 255 words / 15 wpm = <<255/15=17>>17 minutes to type without taking a break. How many minutes does it take Lily to type 255 words? ** Since Lily takes a break after 10 minutes of typing she takes 17 minutes + 2 minutes = 19 minutes #### 19 The space station, Lupus-1, is an enormous spacecraft made up of three identical cylindrical structures that house the living quarters for the crew. The three cylindrical structures are linked together by a series of tunnels that hold them together and allow the crew to move between cylinders. Each cylindrical structure contains 12 bedrooms, 7 bathrooms, and several kitchens. If the entire space station has 72 rooms, how many kitchens are there on the entire space station? How many rooms are in each individual cylindrical structure? ** If there are 3 identical cylindrical structures, with a combined total of 72 rooms, then each individual cylindrical structure contains 72/3=<<72/3=24>>24 rooms. How many kitchens are in each individual cylindrical structure? ** In each 24-room cylindrical structure, there are 24-12-7=<<24-12-7=5>>5 kitchens. How many kitchens are on the entire space station? ** Thus, the entire, three-cylinder space station contains a total of 3*5=<<3*5=15>>15 kitchens. #### 15
