Q: Charles is jogging while listening to his favorite album. He runs at 6 MPH when he's got music on and 4 MPH when he doesn't. His album is 40 minutes long. How many minutes will it take him to jog 6 miles?
A: 70
Step-by-step reasoning process: He runs at .1 miles per minute because 6 / 60 = .1. While the album is playing he can run 4 miles because 40 x .1 = 4. He has to run 2 miles without the album because 6 - 4 = 2. Without music he runs 1 / 15 miles per minute because 4 / 60 = 1 / 15. He will run the remaining 2 miles in 30 minutes because 2 / (1 / 15) = 30. It will take him 70 minutes in total because 40 + 30 = 70.

Q: Chester must deliver ten bales of hay to Farmer Brown. Farmer Brown wants Chester to supply better quality hay and double the delivery of bales of hay. If the previous hay cost $15 per bale, and the better quality one cost $18 per bale, how much more money will Farmer Brown need to meet his own new requirements?
A: 210
Step-by-step reasoning process: The hay previously cost $15 per bale so 10 bales would cost $15 * 10 = $150. Double 10 bales is 10 * 2 = 20 bales. Better quality hay cost $18 per bale so 20 bales would cost $18 * 20 = $360. Farmer Brown would need $360 - $150 = $210 more.

Q: Jaynie wants to make leis for the graduation party. It will take 2 and half dozen plumeria flowers to make 1 lei. If she wants to make 4 leis, how many plumeria flowers must she pick from the trees in her yard?
A: 120
Step-by-step reasoning process: To make 1 lei, Jaynie will need 2.5 x 12 = 30 plumeria flowers. To make 4 leis, she will need to pick 30 x 4 = 120 plumeria flowers from the trees.

Q: Chance boarded a plane departing from London to New York at 6:00 a.m. ET on Monday. He arrived in New York 18 hours later. If he took another plane flying to Cape town the day he arrived in New York and arrived in Cape town at 10:00 a.m ET on Tuesday, calculate the number of hours his flight took from New York to cape town.
A: 10
Step-by-step reasoning process: Eighteen hours later, after departing from London, Chance arrived in New York at 6:00 + 18 hours = 00:00 on Tuesday. If he arrived in cape town at 10:00 p.m. on Tuesday, his flight took 10:00 - 00:00 = 10 hours.
