240,000 miles / hourÂ˛ Average acceleration can be calculated by dividing the change in speed by the elapsed time. Since the dragster's speed was 0 when the light turned green, the change in speed is simply 300 mph. Now, divide that by the time: 300 mph / 0.00125 hours = 240,000 miles / hourÂ˛ By the way, 0.00125 hours is just 4.5 seconds!
