The car traveling on the longer route travels 2 miles per hour slower than the other car and it takes it 6 hours for the trip. If the car with the shorter route takes 5 hours for its trip, find the length of each route. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = the speed of the car taking
the shorter route in mi/hr = the speed of the cat taking the
longer route in mi/hr
Let = the distance of the shorter route in miles = the distance of the longer route in miles
