[Question]Jill can run up a hill at 9 feet/second and down a hill at 12 feet/second. How long does it take her to run up and down a 900 foot hill?
[Answer]First find the time it takes Jill to run up the hill: 900 feet / 9 feet / second = 100 seconds. Then find the time it takes Jill to run down the hill: 900 feet / 12 feet / second = 75 seconds. Then add the two times to find Jill's total time: 100 seconds + 75 seconds = 175 seconds. The answer is 175.

[Question]John jogs at a speed of 4 miles per hour when he runs alone, but runs at 6 miles per hour when he is being dragged by his 100-pound German Shepherd dog. If John and his dog go on a run together for 30 minutes, and then John runs for an additional 30 minutes by himself, how far will John have traveled?
[Answer]
John runs at 6 miles per hour for 0.5 hours, for a distance of 6 * 0.5 = 3 miles. Then John runs at 4 miles per hour for 0.5 hours, for a distance of 4 * 0.5 = 2 miles. In total, John runs 3 + 2 = 5 miles. The answer is 5.
