Question

A crew of highway workers paved 2/15 mile in 20 minutes. If they work at the same rate, what portion of a mile will they pave in one hour?

Answer 1

Divide
`(2)/(15)` by 20 to get how many miles the workers paved per minute. Remember that 20 =
`(20)/(1)`


`(2)/(15)` ÷
`(20)/(1) =`
`(1)/(150)`

The workers paves
`(1)/(150)` miles per minute


`(1)/(150) * (60)/(1) = (60)/(150) = (2)/(5)`

The workers paved
`(2)/(5)` miles in 1 hour =)
