Q: Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour. In minutes, how much faster will Mac run a 24 mile race?
A: First find how fast each runs. Apple = 24 miles / 3 miles per hour = 8 hours. Mac = 24 miles / 4 miles per hour = 6 hours. Mac runs 8 hours - 6 hours = 2 hours faster. 1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = 120 minutes. The answer is 120.
Question: The P.T.O. decided to provide shirts for the elementary students for track and field day. Each grade was given a different color. 101 Kindergartners wore orange shirts that cost $5.80 each. 113 first graders wore yellow shirts that cost $5 each. 107 second graders wore blue shirts that cost $5.60 each. 108 third graders wore green shirts that cost $5.25 each. How much did the P.T.O. spend on shirts for field day?
Answer: The cost for 101 Kindergarten shirts x $5.80 = $585.80. The cost for 113 first grade shirts x $5 = $565. The cost for 107 second grade shirts x $5.60 = $599.20. The cost for 108 third grade shirts x $5.25 = $567. The total cost of the shirts was $585.80 + $565 + $599.20 + $567 = $2,317. The answer is 2317.

[Question]Daisy’s milk cow provides 16 cups of milk per day. 75% of the milk is consumed by Daisy’s kids. Daisy uses 50% of the remaining milk to cook with. How much milk is left over?
[Answer]
The cow provides 16 cups of milk per day and the kids consume 75% so they drink 16 * .75 = 12 cups of milk. The cow provides 16 cups of milk and the kids drink 12 cups leaving 16 - 12 = 4 cups of milk. Daisy uses 50% of the remaining 4 cups of milk to cook with so she uses .50 * 4 = 2 cups of milk. She had 4 cups of milk and used 2 cups to cook with so that leaves 4 - 2 = 2 cups of milk. The answer is 2.
