Question

Amber coaches soccer and volleyball. She coaches both sports for a total of 7 hours each day. The soccer practice lasts 1 hour more than twice as long as the volleyball practice?

Answer 1

Soccer practice is `4` hours long and volleyball practice is `3` hours long.

Explanation:

Let

• Volleyball `= 2x`
• Soccer `=1+2x`

Then

`7=(1+2x)+2x`
`7=1+4x`
`6=4x`
`3/2=x`
`1.5=x`

So

• Volleyball `= 2 * 1.5`
• Soccer `=1+2 * 1.5`
