(60 mi/hr) x (5,280 ft/mi) x (1 hr / 60 min) x (1 meter / 3.28084 feet)= (60 x 5,280) / (60 x 3.28084) (mi - ft - hr - meter / hr - mi - min - ft)= 1609.344 meters/minute
180 mi/hr (5280 ft/1 mi)(1 hr/3600 sec.) = 264 feet per second ------------------------------

20 mi/h * (1 h / 3600 s) * (5280 ft / 1 mi) = 29.33 ft/sec
1 mile = 5,280 feet1 hour = 3,600 seconds(1 mi/hr) x (5,280 ft/mi) x (hr/3,600 sec) = (1 x 5,280 / 3,600) (mi - ft - hr / hr - mi - sec) =1.4667 ft/sec (rounded) = 1foot 5.6inches per second
(60 mi/hr) x (5,280 ft/mi) x (1 hr / 60 min) x (1 meter / 3.28084 feet)= (60 x 5,280) / (60 x 3.28084) (mi - ft - hr - meter / hr - mi - min - ft)= 1609.344 meters/minute
