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.How long is each afternoon practice?

Sagot :

The afternoon practice is 2 hours long.

Let x be the hours the team practices in the afternoon.

Number of hours per day

Since the team practices 3 hours in the morning, the total number of hours the team practices per day is T = 3 + x

Also, the team practices 4 days per week.

Number of hours per week

So, the total number of hours the team practices per week = number of hours per day number of days per week = T × 4

= (3 + x)4

= 4(3 + x)

Hours of afternoon practice

Now, the total number of hours the team practices each week is 20.

So, 4(3 + x) = 20

3 + x = 20/4

3 + x = 5

x = 5 - 3

x = 2

So, the afternoon practice is 2 hours long.
