1. Write these down while you wait:
1 hr = 60 min = 3600 sec
1 km = 1000 m  mile
1 mile = 5280 ft = 1760 yards  1609 m
1 m  ft
1 yard = 3 feet
Shortcuts:
1 m/s = 3.6 km/hr  mph, (mph = miles/hour)
1 mph  1.47 f/s ( …)
1 f/s  .682 mph ( …)
Answer This Question:
How many feet per second is 30 mph? (use any method you want – including help from others – but have an answer)

(30 mph)( ) = 44 ft/s
(30 mi)(5280 ft)(1 hr) = 44 ft/s
( hr )( 1 mi )(3600 s)
