Question: Barry and his friend, Jim, went horseback riding across central Texas. They traveled at 5 miles per hour for 7 hours, and then stopped for the evening. The next day, they traveled at 6 miles per hour for 6 hours, and then at half that speed for another three hours, before stopping to rest for the night. On the third and final day, they traveled for 5 hours at 7 miles per hour. In total, how far did they travel, in miles, during their horseback riding trip?
Answer: On the first day, they traveled 5 * 7 = 35 miles. On the first part of the second day, they traveled 6 * 6 = 36 miles. The second part of the second day, at half their morning speed, they traveled (6 / 2) * 3 = 9 miles. On the final day, they traveled 5 * 7 = 35 miles. In total, they traveled 35 + 36 + 9 + 35 = 115 miles. The answer is 115.

Q: Josh wants to build a square sandbox that is 3 ft long, 3 ft wide for his son. He can buy sand in 3 sq ft bags for $4.00 a bag. How much will it cost him to fill up the sandbox?
A: The sandbox is 3' long, 3' wide so the sq footage of the sandbox is 3 * 3 = 9 sq ft. He needs 9 sq ft of sand to fill the sandbox and he can buy it in 3 sq ft bags so he needs 9 / 3 = 3 bags of sand. The sand costs $4.00 a bag and he needs 3 bags so it will cost him 4 * 3 = $12.00 in sand. The answer is 12.
Question: Dawn, Lydia, and Donna have a total of 200 bananas. Dawn has 40 more bananas than Lydia. If Lydia has 60 bananas, how many bananas does Donna have?
