2) A train has a normal speed of 60 mph. When putting on brakes, it can decelerate at a rate of 2 mph/s and when starting can accelerate at a rate of 1 mph/s. Calculate the minimum distance between two stations for which the train just can reach its 60 mph speed before putting on the brakes again. ANS. 0.75 miles
