**Reiny**, Tuesday, December 4, 2012 at 11:39pm50 miles/(1 hour) , -----> 1 mile = 5280 ft, 1 hr = 3600 seconds

= 50(5280) ft/(3600 seconds)

= 220/3 ft/sec

= 73.333.. ft/sec

= appr 73 ft/sec

a quick estimate of miles/hr to ft/sec is to simply multiply the given mph by 1.5

( 5280/3600) = = 1.47 or appr 1.5 )
