Problema Solution
Deandre and Dylan are 138 miles apart, traveling towards each other. If Dylan travels 15 mph and Deandre travels 8 mph how long until they meet?
Answer provided by our tutors
let
v1 = 15 mph the speed of Dylan
v2 = 8 mph the speed of Deandre
d = 138 mi the distance between them
t = the time of the travel
since speed = distance/time follows distance = speed*time
v1*t + v2*t = d
15t + 8t = 138
by solving we find:
t = 6 hr
