7-29.

Write an equation in which x represents the time spent swimming and 2x represents the time spent playing volleyball.
x + 2x = 4.5

Solve for the time spent swimming, x, then double that number to find the time spent playing volleyball.

3x = 4.5
x = 1.5

1.5 hours spent swimming and 3 hours spent playing volleyball.
