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?

Question

Identify total practice hours:  Step 1: Identify total practice hours per day. Since the team practices 4 days a week for a total of 20 hours, each day they practice 20 / 4 = 5 hours.Calculate morning practice hours:  Step 2: Calculate morning practice hours per week. They practice 3 hours each morning, 4 days a week, so 3 hours/day * 4 days = 12 hours per week in the morning.Determine afternoon practice hours:  Step 3: Determine afternoon practice hours per week. Total weekly hours (20 hours) minus morning hours (12 hours) gives 20 - 12 = 8 hours per week in the afternoon.Find afternoon practice length:  Step 4: Find the length of each afternoon practice session. Since they practice in the afternoon 4 days a week, each session is 8 hours / 4 days = 2 hours per session.
