How fast is your car going? Calculating the speed (average speed) of a racecar is pretty simple. The formula is:
Average Speed = Distance/Time
To plug in some numbers, our distance will be 65.625 feet (ft) (official distance) and our time will be 1.22 seconds (s) (a pretty fast race time).
65.625 ft/1.22 s = 53.79 ft/s
To convert your speed to miles per hour (mph) we have to know a few things. There are:
5280 feet in a mile
3600 seconds in an hour
Plug in those numbers and we can figure out the speed in mph.
53.79 ft/s x 3600 s/5280 ft = 36.68 mph
Our dragster is roughly 1/20th the size of a top-fuel dragster.
If it were full size, (20 x 36.68 mph)
