Question

Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 42 miles at a speed of 6 mph, while Bob's motorboat traveled 91 miles at a speed of 13 mph. For how long were Niles and Bob traveling?

Answer 1

7 hours.

Explanation:

All you need to do is divide because
`(distance)/(speed)` = time:

`(42)/(6)` = 7 and
`(91)/(13)` = 7
