The conversion for 1 MPH is 1.4666 feet per second. Mark two chalk lines on your street 100 feet apart and get a good stopwatch. Time the truck from mark to mark.
Divide 100' by that time, let's say it's 3 seconds.
100'/3sec=33.3 feet per second(fps)
Compare that to the given (1.4666fps=1mph)
33.3fps/1.466fps=22.7mph
Easy!!
