A driver involved in an accident claims he was going only 42 MPH. When police tested his car, they found that when his brakes were applied at 42 MPH, the car skidded 160 feet before coming to a stop. However, the driver's skid marks at the accident scene measured 210 feet. Assuming the same constant deceleration, determine the speed he was actually travelling just prior to the accident?
