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?
3h +420
4h +3 20
4(h+3) 20
3(h+ 4) = 20
How long is each afternoon practice?
Write your answer as a whole number or a simplified fraction.

Answer 1

The correct equation to use in this scenario is: 4(h+3) = 20

To find the length of each afternoon practice, we will solve for h:

4(h+3) = 20
4h + 12 = 20
4h = 8
h = 2

Therefore, each afternoon practice is 2 hours long.
