Question

A crew of highway workers paved 1/15 miles in 10 minutes.If they work at the same rate ,what portion of mile will they pave in one hour?

Answer 1

`2/5`miles

Explanation:

Think of it as a ratio

For every 10 minutes, they pave `1/15` miles
Therefore, in one hour which is 60 minutes, they will have paved `1/15times6` miles since 60 minutes is `6times10`minutes

`1/15times6=2/5`miles

Answer 2

2/5

Explanation:

find the part of mile done in one minute
`(1/15)/(10/1)` = `(1/15)*(1/10)` = `1/150`mile in 1 minute
`therefore`in 60 min = `1/150 *60` = `60/150`= `2/5` of a mile in 1 hr.
