How do you convert $60$ miles$/$hour to ft$/$sec $?$

Answer 1

We have to know what miles is called and also the transformation formula of miles to ft. Mile is the unit of distance or displacement. This unit originated from Roman mille passus. One mile is equal to $1609.34m$. Hour is the unit of time. We also know that sixty seconds is equal to one minute. Again sixty minutes is equal to one hour.

Complete answer:
We know that,
$1mile = 1609.34m$
$\Rightarrow 1mile = \dfrac{{1609.34}}{{0.3048}}$
$\therefore 1mile = 5279.987ft$
Therefore $60$ miles per hour is equal to $(60 \times 5279.987)ft/3600\sec$ which is equal to $87.999ft/\sec$.

So the answer is $60$ miles$/$hour is equal to $88$ft $/$ sec.
