Question

A runner and a walker depart from the same point going in opposite directions on a circular track that is 1 mile long. The runner travels at 9 mph and the walker at 3 mph. After how many minutes will they pass each other?

I know the answer is 5 but I don't know how to get it

Answer 1

clearly the runner travels 3/4 mile and the walker 1/4 mile.

So, how long does it take?

(1/4 mi)/(3 mi/hr) = 1/12 hr = 5 min.
