proportional ratios with exponents - Need Help!! A walker's speed, v, is proportional to the ratio of his leg length, L, and the period of the repeating motion of his legs, T, that is, v ∝ L/T. If the period is measured to be proportional to Lp, where p = 4/5, what power of L must the speed be proportional to? I have absolutely no idea how to do this problem. I've tried it a couple times and I'm getting no where with it. Please help!!! The more you could explain the answer the more helpful it would be as well!
