You can put this solution on YOUR website! In units:
( mi / hr ) x ( ft / mi ) x ( hr / min ) = ft / min
and
ft / ( ft / min ) = min
------------------ ft/min min
and
( min ) x ( sec/min ) = sec sec
It will take a car .124 sec to travel 10
ft at 55 mi/hr
------------------------------
At 60 mi/hr, ft/min min sec
It will take a car .114 sec to travel 10
ft at 60 mi/hr
