convert 50 miles per hour in feetvper second(round to the nearest whole.)

• math -

50 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 )

• math -

(50 miles x 5280 feet x 1 hour x 1 minute) /
(1 hour x 1 mile x 60 minutes x 60 seconds)=
73 feet per second
