Q: Mark has two pets, a hare that runs 10 feet/second and a turtle that crawls 1 foot/second. If they're going to run a 20 foot-race, how much of a head start (in seconds) does the turtle need to finish in a tie?
A: We can find how long the hare spends running by dividing the distance of the race by the hare's speed: 20 feet / 10 feet / second = 2 seconds. We can do the same for the turtle: 20 feet / 1 foot / second = 20 seconds. Finally, subtract the hare's run time from the turtle's run time to find the length of the head start the turtle needs: 20 seconds - 2 seconds = 18 seconds. The answer is 18.
Question: A new movie gets released and makes $120 million in the box office for its opening weekend. It ends up making 3.5 times that much during its entire run. If the production company gets to keep 60%, how much profit did they make if the movie cost $60 million to produce?
Answer: Over the movies run it made 120 * 3.5 = 420 million. So the production company made 420,000,000 * .6 = $252,000,000. So they got a profit of 252,000,000 - 60,000,000 = $192,000,000. The answer is 192000000.

Q: Mike can type 65 words per minute. Due to a minor accident, Mike cannot use his right hand for a while so that his typing speed is now 20 words less per minute. If he is supposed to type a document with 810 words, how many minutes will it take him to finish typing the document?
A: After the accident, Mike can only type 65 words / minute - 20 words / minute = 45 words / minute. So, he will be able to finish typing the document in 810 words / 45 words / minute = 18 minutes. The answer is 18.
Question: A single kabob stick has 4 cubes of beef. A slab of beef that costs $25 can be cut into 80 cubes. How much must Simon spend to make 40 kabob sticks?

Q: A local farmer is paying 4 kids to help plant rows of corn. Every row of corn contains 70 ears. A bag of corn seeds contains 48 seeds and you need 2 seeds per ear of corn. He pays the kids $1.5 per row. Afterward, the kids are so hungry that they end up spending half their money on dinner. The dinner cost $36 per kid. How many bags of corn seeds did each kid use?
A:
The dinner cost $144 dollars because 4 x 36 = 144. The kids earned $288 in total because 144 x 2 = 288. They planted 192 rows of corn because 288 / 1.5 = 192. They planted 13,440 ears of corn in total because 192 x 70 = 13,440. They each planted 3,360 ears of corn because 13,440 / 4 = 3,360. They each planted 6,720 seeds because 3,360 x 2 = 6,720. They each used 140 bags of seeds because 6,720 / 48 = 140. The answer is 140.
