If a runner who runs at a constant speed of p miles per hour runs a mile in exactly p minutes, what is the integer closest to the value of p?

Can I get a step by step or an explanation, please?

Solve for p:

p/60 = 1/p

Cross multiply:

p^2 = 60

Take the square root of both sides:

**p = 2 sqrt(15) = 7.745967 - miles per hour =1 mile in exactly in 7.745967 minutes.**
