Lizzy: Janet goes to the gym for 5 hours a week. She goes Monday, Tuesday, Wednesday, and Friday. She spends an hour and a half each day on Monday and Wednesday. If she spends the same amount of time at the gym on Tuesday and Friday how many hours is she at the gym on Friday?.
Me: Hmmm, let me think. I think this is the detailed solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Between Monday and Wednesday, she spends 1.5 hours + 1.5 hours = 3 hours. That means she has 5 hours - 3 hours = 2 hours left for Tuesday and Wednesday. She spends 2 hours / 2 = 1 hour on Friday. Final answer: 1.
