a road crew can repave 1/15 miles of road each hour. they must repave a road that is 3/5 miles long. how long will it take the crew to repave the road?

9 hours

Step-by-step explanation:

For this problem, we simply need to rewrite the goal length, 3/5 miles, into our ratio of time length equivalence, 1 hour per 1/15 miles.  To do this we find the common denominator to be 15 and rewrite it as so:

3/5

= 3*3 / 5 * 3

= 9 / 15

And since it takes 1 hour per 1/15 mile of road, we can perform the division to find the amount of time:

9/15 / 1/15

= 9/15 * 15/1

= ( 9 * 15 ) / ( 15 * 1 )

= 9 / 1

= 9

Hence, it will take the crew 9 hours to repave the road.

Cheers.
