TMI. To find the speed, v, all you need are the mass, M, and the

**k**inetic energy, T, because: T = ½Mv² So just solve that for v, and then plug in the values for M and T.1 Answers · Science & Mathematics · 07/01/2015

you need to find the time spent at each speed say the hill is 10 km long 10 / 41 = 0.2439 time up hill 10 / 62 = 0.1613 time down hill 0.2439 + 0.1613 = 0.4052 total time 0.2439 / 0.4052 = 0.6019 %age of time spent going up hill 0.1613 / 0.4052 = 0.3981 %age of time spent going down hill 41 X 0.6019 = 24.6779 62...
