A car driving cross-country traveled 180 miles in 4 hours. At this rate of speed, how many miles further will the car travel in the next 3 hours?

The car drives 180 miles in 4 hours, so its average speed is 180 miles / 4 hours =

<<180/4=45>>45 miles per hour. In the next 3 hours, the car will drive 45 miles/hour * 3 hours = <<45*3=135>>135 miles. #### 135 Sam and Drew have a combined age of 54. Sam is half of Drew's age. How old is Sam? Let x be Drew's age. Sam is (1/2)x x+(1/2)x=54 (3/2)x=54 3x=108 x=<<36=36>>36 Sam is 36/2=<<36/2=18>>18 years old #### 18 Nadine went to a garage sale and spent $56. She bought a table for $34 and 2 chairs. Each chair cost the same amount. How much did one chair cost? Nadine spent $56 - $34 for the table = $<<56-34=22>>22 on chairs. The cost of the chairs was equal, so one chair cost $22 / 2 = $<<22/2=11>>11. #### 11 James is trying to create a new breed of kittens with extra-long tails. Each generation of kittens he breeds has a tail 25% longer than the last generation. If the first generation has tails 16 cm long, how long are the third generation's tails? First find how much longer the second generation's tails are: 25% * 16 cm = <<25*.01*16=4>>4 cm Then add that length to the first generation's tail length to find the second generation's tail length: 4 cm + 16 cm = <<4+16=20>>20 cm Then find how much longer the third generation's tails are: 25% * 20 cm = <<25*.01*20=5>>5 cm Then add that length to the second generation's tail length to find the third generation's tail length: 5 cm + 20 cm = <<5+20=25>>25 cm #### 25 Brendan went fishing with his dad. Brenden caught 8 fish in the morning. He threw 3 back that were too small. He caught 5 more in the afternoon. Brendan’s dad caught 13 fish. How many fish did they catch in all? Brenden caught 8 fish in the morning + 5 in the afternoon = <<8+5=13>>13 fish. After throwing the small fish back, Brenden has 13 – 3 = <<13-3=10>>10 fish. Together, Brenden and his dad caught 10 + 13 = <<10+13=23>>23 fish. #### 23 Cherry put up a delivery service. She charges $2.50 for a 3-5 kilograms cargo and $4 for a 6-8 kilograms cargo. If she delivers four 5 kilograms cargo and two 8 kilograms cargo per day, how much money will she earn in a week? Cherry earns $2.50 x 4= $<<2.5*4=10>>10 after delivering four 5 kilograms of cargo per day. She earns $4 x 2= $<<4*2=8>>8 after delivering two 8 kilograms of cargo per day. So, her total earning per day is $8+$10= $<<8+10=18>>18. Therefore, she will earn $18 x 7= $<<18*7=126>>126 in a week. #### 126 It is raining outside and Bill puts his empty fish tank in his yard to let it fill with rainwater. It starts raining at 1 pm. 2 inches of rainfall in the first hour. For the next four hours, it rains at a rate of 1 inch per hour. It then rains at three inches per hour for the rest of the day. If the fish tank is 18 inches tall, at what time will it be filled with rainwater. At 2 pm there are 2 inches of rain in the tank. At 6pm, there are 2 + 4 * 1 = <<2+4*1=6>>6 inches of rain in the tank. That means that there are 18 - 6 = <<18-6=12>>12 inches of tank that still need to be filled as of 6 pm. It will take 12 / 3 = <<12/3=4>>4 hours to finish filling the tank. The tank will be filled at 6 + 4 = <<6+4=10>>10pm. #### 10 James finds 3 bills in his pocket. They are all 20s. If he already had $75 in his wallet how much money doe he have now? He found 3*20=$<<3*20=60>>60 So now he has 60+75=$<<60+75=135>>135 #### 135 Mary has 3 times as much candy as Megan. Mary then adds 10 more pieces of candy to her collection. If Megan has 5 pieces of candy, how many does Mary have in total? Mary has 5*3=<<5*3=15>>15 pieces of candy. She adds more, which brings her total to 15+10=<<15+10=25>>25 pieces of candy. #### 25 A hotel had operations expenses totaling $100. If the hotel received clients whose total payments for services offered totaled 3/4 of the cost of the operations, calculate the loss the hotel incurred. The total payment from the clients who used the hotel's services is 3/4*100=$<<3/4*100=75>>75 The hotel incurred a loss of $100-$75=$<<100-75=25>>25 #### 25
