To calculate just how much sooner you could stop if you saved a second, use the conversion factor of 1 mph = 1.46 feet per second.
So, if you were traveling at 55 mph, you are doing 81 feet per second. Learning to increase your reaction time by habitually covering the brake could theoretically stop you from 55 mph about six or seven car lengths sooner.
Likewise, if you were doing 35 mph, a second equals 51 feet saved in stopping distance, or about 4 cars lengths. If you were doing 80 mph, it would equal 117 feet per second, or more than a third of a football field.
whoa...55mph is approx 85km/hr...its like ma normal speed in a blank road...neva wondered...i speed throu 81 ft/s...in that speed...its almost teleportation lol!!
