Question

While preparing for a marathon, a runner determined that he could run 1/6 of a mile in 4/5 of a minute. If the runner ran for 1 mile how many minutes would it take?

Answer 1

4 4/5 minutes

Explanation:

create a proportion:

`(1/6)/(4/5)` =
`(1)/(t)`

cross-multiply: t = 4

6 5

cross-multiply: 5t = 24

t = 24/5 or 4 4/5 min
