The distance between Arizona and New York is around 2,000 miles by plane. The distance between the 2 different US states increases by 40% if someone decides to drive instead of flying. Missouri is midway between Arizona and New York. How far away is Missouri from New York if someone decides to go by car?

The distance between Arizona and New York is 2,000 miles by plane.

The distance between Arizona and New York is 40% greater by car, which is 40% * 2,000 =

<<40*.01*2000=800>>800 miles. This results in a total of 2,000 + 800 = <<2000+800=2800>>2,800 miles between Arizona and New York by car. If Missouri is in the middle of the way between Arizona and New York, someone would drive half of the distance to go from Missouri to New York, which is 2,800 / 2 = <<2800/2=1400>>1,400. #### 1400 Anna is reading a 31-chapter textbook, but she skips all the chapters that are divisible by 3. If it takes her 20 minutes to read each chapter, how many hours does she spend reading total? First divide 32 by 3, ignoring the remainder, to find how many chapters in the book are divisible by 3: 31 / 3 = 10.33..., which means 10 chapters are divisible by 3 Then subtract that number from the total number of chapters to find how many chapters she reads: 31 chapters - 10 chapters = <<31-10=21>>21 chapters Then multiply the number chapters by the time to read each chapter to find the total time she spends reading: 21 chapters * 20 minutes/chapter = <<21*20=420>>420 minutes Then divide that time by the number of minutes per movie to find the total time spent reading in hours: 420 minutes / 60 minutes/hour = <<420/60=7>>7 hours #### 7 Tony exercises every morning by walking 3 miles carrying a 25-pound backpack, then he runs another 10 miles without the backpack. If he walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour, how many hours each week does he spend exercising? Tony walks 3 miles at 3 miles per hour for 3/3=1 hour. Tony also runs 10 miles at 5 miles per hour for 10/5=<<10/5=2>>2 hours. Thus, each day he exercises for 1+2=<<3=3>>3 hours. Over the course of one week, he exercises for 3*7=<<3*7=21>>21 hours. #### 21 Ali and Sara ate 80 small apples combined. Ali ate 4 times more apples than Sara. How many apples did Sara eat? Let A be the number of apples Ali ate and S be the number of apples Sara ate. We have: A + S = 80 apples And: A = <<4=4>>4S Which means: 4S + S = 80 So: 5S = 80 So the number of apples Sara ate is: S = 80 / 5= <<80/5=16>>16 apples #### 16 Francine wants to know if a local chemical plant is releasing toxic waste that makes the frogs mutate. In one local pond, she catches 5 frogs with extra legs, 2 frogs with 2 heads, two frogs that are bright red, and 18 normal frogs. What percentage of the frogs have mutated, rounded to the nearest integer? First add up the numbers of the three kinds of mutant frog: 5 frogs + 2 frogs + 2 frogs = <<5+2+2=9>>9 frogs Then add that number to the number of normal frogs to find the total number of frogs: 9 frogs + 18 frogs = <<9+18=27>>27 frogs Finally, divide the number of mutant frogs by the total number of frogs and multiply by 100% to find the percentage of frogs that are mutants: 9 frogs / 27 frogs * 100% = 33.333...%, which rounds to 33% #### 33 Mary is paying her monthly garbage bill for a month with exactly four weeks. The garbage company charges Mary $10 per trash bin and $5 per recycling bin every week, and Mary has 2 trash bins and 1 recycling bin. They're giving her an 18% discount on the whole bill before fines for being elderly, but also charging her a $20 fine for putting inappropriate items in a recycling bin. How much is Mary's garbage bill? First find how much Mary pays weekly for the trash bins: $10/trash bin * 2 trash bins = $<<10*2=20>>20 Then add this to the cost of the recycling bin: $20 + $5 = $<<20+5=25>>25 Then multiply the week cost by the number of weeks per month to find the monthly cost: $25/week * 4 weeks/month = $<<25*4=100>>100/month Now calculate Mary's senior discount: 18% * $100 = $<<18*.01*100=18>>18 Now subtract the discount and add the fine to find the total monthly cost: $100 - $18 + $20 = $<<100-18+20=102>>102 #### 102 There are 3 bicycles, 4 tricycles and 7 unicycles in the garage at Zoe's house. Each bicycle has 2 wheels, each tricycle has 3 wheels and each unicycle has 1 wheel. How many wheels are there in all? The number of bicycle wheels is 2 × 3 = <<2*3=6>>6. The number of tricycle wheels is 3 × 4 = <<3*4=12>>12. The number of unicycle wheels is 1 × 7 = <<1*7=7>>7. The total number of wheels is 6 + 12 + 7 = <<6+12+7=25>>25. #### 25 A zoo has 21 penguins and twice as many polar bears? How many total animals do they have? There are 21*2=<<21*2=42>>42 polar bears So the total 21+42=<<21+42=63>>63 total animals #### 63 James writes from 1 PM to 4 PM every night. He can write 5 pages per hour. How many weeks will it take to finish his 735-page book? He writes for 4-1=<<4-1=3>>3 hours per day That means he writes 3*5=<<3*5=15>>15 pages per day So it would take him 735/15=<<735/15=49>>49 days That means it will take 49/7=<<49/7=7>>7 weeks #### 7 Sid takes $48 with him on a shopping trip to the mall. He spent some of his money on computer accessories and another $8 on snacks. After these purchases, he only has $4 more than half of his original money left. How much did he spend on computer accessories? Half of Sid's original money is $48/2 = $<<48/2=24>>24. Sid has only $24 + $4 = $<<24+4=28>>28 left after his purchases. He had $28 + $8 = $<<28+8=36>>36 before he spent $8 on snacks. So, Sid spent $48 - $36 = $<<48-36=12>>12 on computer accessories. #### 12
