If we let

x and t1 as the distance traveled and the travel time, respectively using the first route

y and t2 as the distance traveled and the travel time, respectively using the second route

Then we have the equations:

x = 25 t1

y = 30 t2

y = x + 5

t2 = t1 - 10/60

Solving of x, y, t1 and t2

x = 50 mi

y = 55 mi

t1 = 2 hr

t2 = 1.83 hr
