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.
