Q: The cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000. What's the cost of transporting three times as many cement bags, each weighing 3/5 times as many kgs?
A: Three times as many cement bags is 3 * 80 = 240 cement bags. If a bag of cement weighs 50 kg, 3 / 5 times as much weight is 3 / 5 * 50 = 30 kgs. If the cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000, the cost of transporting one bag of cement weighing 50 kg is $6000 / 80 = $75. Since a bag weighing 50 kgs costs $75 to transport, a bag weighing 30 kgs will cost 30 * $75 / 50 = $45 to transport. The cost of transporting 240 cement bags each weighing 30 kgs is $45 * 240 = $10800. The answer is 10800.
Question: Jeff has a shelter where he currently takes care of 20 cats. On Monday he found 2 kittens in a box and took them to the shelter. On Tuesday he found 1 more cat with a leg injury. On Wednesday 3 people adopted 2 cats each. How many cats does Jeff currently have in his shelter?
Answer: Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = 23 cats. 3 people took a total of 3 * 2 = 6 cats. After Wednesday, Jeff was left with 23 - 6 = 17 cats. The answer is 17.
[Question]Marcus spends 20 minutes giving his dog a bath and half as long blow-drying her. Then he takes her for a walk along a 3-mile trail. If Marcus walks at 6 miles per hour, how much time does he spend with his dog total?
[Answer]First find the total amount of time Marcus spends blow - drying his dog: 20 minutes / 2 = 10 minutes. Then find the time Marcus spends walking: 3 miles / 6 miles / hour = .5 hours. Then convert that time to minutes: .5 hours * 60 minutes / hour = 30 minutes. Then add up the time Marcus spends washing, drying and walking to find the total time: 10 minutes + 20 minutes + 30 minutes = 60 minutes. The answer is 60.
[Question]Moses and Tiffany want to see who is faster. But instead of a race, they just start running down the block. Tiffany runs 6 blocks in 3 minutes. Moses runs 12 blocks in 8 minutes. What is the speed (defined as blocks per minute) of the runner with the higher average speed?
[Answer]
Tiffany runs 2 blocks per minute because 6 / 3 = 2. Moses runs 1.5 blocks per minute because 12 / 8 = 1.5. The runner with the highest average speed is Tiffany because 2 > 1.5. The answer is 2.
