Problema Solution
Two people start walking at the same time in the same direction. One person walks at 5 mph and the other person walks at 2 mph. In how many hours will they be .75 miles apart
Answer provided by our tutors
let
v1 = 5 mph the speed of the first person
v2 = 2 mph the speed of the second person
t = the time the walk until they are 0.75 miles apart
since distance = speed*time and they are walking the same direction we have:
v1*t - v2*t = 0.75
5t - 2t = 0.75
by solving we find:
t = 0.25 h
t = 0.25*60 min
t = 15 min

after 0.25 hours or 15 minutes the two people will be 0.75 miles apart.
