It took Max 3.5 hours to cover a certain route walking at a rate of 2.4 mph. How long would it take Max to cover the same route walking 3 mph?

It takes 2.8 hours for Max to cover the same route by walking with 3 mph. The certain route has 8.4 miles distance which can be acquired by multiplying the velocity and the amount of time (3.5 x 2.4). Then the new amount of time can be acquired by dividing the certain route distance by the new velocity (8.4 / 3). All of the calculations above are calculated with the basic formula of constant velocity which is velocity = change of position/change of time.
