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, vL/T. If the period is measured to be proportional to L^{p, where p = 3/5, what power of L must the speed be proportional to? Enter your answer as a fraction (in lowest terms), first the numerator, then the denominator.}
