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?
Let h be the length of each afternoon practice in hours.
The team practices 4 days per week, so the total length of afternoon practice each week is 4h.
Each afternoon practice is 3 hours long.
Therefore, the total length of afternoon practice each week is 4h * 3 = 12h.
The team practices for a total of 20 hours each week.
Therefore, the equation to find h is 12h = 20.
How long is each afternoon practice?
Write your answer as a whole number or a simplified fraction.
hours
To find the length of each afternoon practice, we need to solve the equation 12h = 20 for h.
Dividing both sides of the equation by 12, we get:
h = 20/12 = 5/3.
Therefore, each afternoon practice is 5/3 hours long, or 1 hour and 40 minutes.
