60

4. anonymous

divide

5. Mertsj

$\frac{7.5 mi}{1 hr}\times\frac{1hr}{60\min}=\frac{7.5 mi}{60 \min}=.125 \frac{mi}{\min}$

6. Popstar30977

is thatt all i have to do or do i have to multiply 1hr x 60min x 60 min @Mertsj

7. Mertsj

Look at the problem setup. The units cancel just like numbers so the hr on top and the hr on the bottom cancel.

ok thanks alot @Mertsj

9. Mertsj

Then on top you have 7.5mi and on bottom you have 60 min.

10. Mertsj

Divide7.5by 60 and get .125 with the units mi/min
