  1. Write these down while you wait: 1 hr = 60 min = 3600 sec 1 km = 1000 m  .6214 mile 1 mile = 5280 ft = 1760 yards  1609 m 1 m  3.281 ft 1 yard = 3 feet Shortcuts: 1 m/s = 3.6 km/hr  2.237 mph, (mph = miles/hour) 1 mph  1.47 f/s (1.46666666…) 1 f/s  .682 mph (.6818181818…)

  2. Example 1: How many feet per second is 30. mph? (Show 3 methods) 1 f/s  .682 mph (.6818181818…) 1 mph  1.47 f/s (1.46666666…) 1 mile = 5280 ft 1 hr = 60 min = 3600 sec 44 f/s

  3. Example 2: Convert 88.0 feet/second to mph 1 f/s  .682 mph (.6818181818…) 1 mph  1.47 f/s (1.46666666…) 1 mile = 5280 ft 1 hr = 60 min = 3600 sec 88 ft( 1 mi )(3600 s) = 60 mph s (5280 ft)( 1 hr ) 60.0 mph 60.0 mph

  4. Convert 110. km/hr to m/s 1000 m = 1 km 3600 s = 1 hr 1 m/s = 3.6 km/hr 110 km (1000 m)( 1 hr ) = 30.55556 m/s hr ( 1 km )(3600 s) 30.6 m/s 30.6 m/s

  5. Convert 27.2 m/s to km/hr 1000 m = 1 km 3600 s = 1 hr 1 m/s = 3.6 km/hr 27.2 m ( 1 km )(3600 s) = 97.92 km/hr s (1000 m)( 1 hr ) 97.9 km/hr 97.9 km/hr
