<h3>Convert feet/seconds to miles/hours.</h3>
- Mile (Mi): Unit of length.
- Foot (Ft): Unit of length.
- Hour (Hr): Unit of time.
- Seconds (S): Unit of time.
Taking into account that:
- <em>1 mi = </em><em>5280 ft</em>
- <em>1 hr = </em><em>3600 se</em>
So 60 <u><em>Feet/Sec = 40.9091 Miles/hours.</em></u>
