Question

Valentina is trying to decide whether to join her school's swim team. During the summer, the team practices 4 days per week. Each of those days, they practice for 3 hours in the morning and practice again in the afternoon. They practice for a total of 20 hours each week.
Which equation can you use to find h, the length of each afternoon practice in hours?
How long is each afternoon practice?

Answers

GPT 3.5
Let h represent the length of each afternoon practice in hours.

Since the team practices for a total of 20 hours each week and each day consists of two 3-hour practices, we can create the equation:

4 days/week * 3 hours/day + 4 days/week * h hours/day = 20 hours/week

12 hours + 4h = 20 hours

Subtract 12 hours from both sides:

4h = 8 hours

Divide by 4 on both sides:

h = 2 hours

Therefore, each afternoon practice is 2 hours long.
