In the formula d = rt, the time t varies inversely with the rate r. A student running at 5 miles per hour runs one lap around the school campus in 8 minutes. If a second student takes 10 minutes to run one lap around the school, how fast is she running?

Answer 1

Plug the numbers into d = rt and solve for distance, then redo and calculate r for the second student. Post your work if you get stuck.
