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.

Question

Which equation can you use to find h, the length of each afternoon practice in hours?
How long is each afternoon practice?

Answer 1

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.
