Problema Solution
a man drives to a location at 35 mph and returns the same way at 40mph. How far is the location if the round trip takes 3 hours?
Answer provided by our tutors
d = rt
rt = rt
35(x) = 40(3-x)
35x = 120 - 40x
75x = 120
x = 1.6
So it takes him 1.6 hours to drive to the location at 35 mph, which would make the distance 56 miles.
