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.

Step-by-step explanation:

All you need to do is divide because $\frac{distance}{speed}$ = time:

$\frac{42}{6}$ = 7 and $\frac{91}{13}$ = 7
