Jenny wants to run 10.0 km and her running pace is 7.5 mi/hr. How many minutes must she run?

I just want a step by step, so I know how to handle these kinds of problems.

Thanks in advance!

How is this undergraduate chemistry; it is more like 5th grade math.  Anyways you have to first convert her running pace which is in miles into km.  7.5 miles per hr is roughly 12.07 km/hr.  Therefore 10/12.07 = 0.8284.  Then 0.8284 * 60 = 49.7 or roughly 50 minutes

That may explain why I've completely forgotten. There's a reason the prof is calling it a review (as you've so kindly noted, there's a math skill deficit). Thanks for the answer, though.
