= (30/(60*60))*8*220*3 ft/sec

1 mi = 5280 ft 1 hr = 60 min 1 min = 60 sec (3 mi)/hr = (3 mi)/hr × (5280 ft)/mi × (1 hr)/(60 min) × (1 min)/(60 sec) = (4.4 ft)/sec Note that the mile, hour, and minute units cancel out, leaving the answer in feet per second.

60 mph = 88 fps 3 mph = 60mph/20 = 88fps/20 = 4.4 fps

Given 3 mph, start there and apply converters 3 mi/1hr (5280ft/mi) (1hr/3600sec) = 4.4 ft/sec ===

3 m/hr * 5280 ft/mile / (60 minutes/hr*60 sec/min). (5280*3/(60*60))=5280/1200=52.8/12 . I think you can handle the arithmetic, right? Follow the units.

(3 miles per hour x 5280 feet per mile)/ (60 minutes per hour x 60 seconds per minute) = 4.4 feet per second.

3 mile/hr * 5,280 ft / 1 mile = 15,840 ft/hr 15,840 ft/hr * 1 hr / 3,600 sec = 4.4 ft/s

Converting 3 mi/hr to feet/sec: 3 mi/hr (5280 ft/mi) (1/60 hr/min) (1/60 min/sec) = 4.4 ft/sec (264 is ft/min)
