Remark

The trick here is to realize that between them they will cover 600 miles


Train one

r = 90 mph

t = ?? [same for both trains]

d = d1


Train Two

r = 75 miles / hour

t = ?? [same for both trains]

d = d2


Equation.

basically d = r*t

d_train1 + d_train2 = total_distance

90*t + 75*t = 600


Combine and solve

165t = 600 Divide by 165

t = 600/165

t = 3.64 hours <<<<<< Answer
