Problema Solution
Hilary went riding in the hills. At one point, however her horse stumbled and was hurt.hilary left the horse and walked back home to call her vet. Hilary figures the horse walks twice as fast as she does. If her horse was hurt 8 miles into her ride and her whole trip took 4 hours total, w fast does Hilary walk?
Answer provided by our tutors
let
v = the rate of Hilary, v>0
2v = the rate of the horse
d = 8 mi the distance in one direction
t = 4 hr the time of the whole tip
since speed = distance/time follows time = distance/speed
d/v + d/(2v) = t
8/v + 8/(2v) = 4
by solving we find:
v = 3 mph

Hilary walked with a rate of 3 mph.
