50seconds

Distance = Rate * Time or, for our purpose Time = Distance/Rate at 50 mph Time = 4.5 miles/50 mph = 0.09 hours = 5.4 minutes ----------------------------- at 40 mph Time = 4.5 miles/40 mph = 0.1125 hours = 6.75 minutes ---------------------------------------------------- 6.75 - 5.4 = 1.35 minutes saved

Distance = Rate * Time or, for our purposes, algebraically thus Time = Distance/Rate for 60 mph Time = 10 miles/60 mph = 0.1666 * 60 minutes = 10 minutes ------------------------------------------------ for 55 mph Time = 10 miles/55 mph = 0.181818 * 60 minutes = 10.90 minutes ------------------------------------------------------ So you save about 9/10 of a minute, but call it 1 minute saved.
