The world record for the hundred meter dash is 9.77 seconds.
What is the corresponding average speed in units of miles per second,
kilometers per hour, feet per second, and miles per hour?
:
Find meters/sec: 100%2F9.77 = 10.2354 m/sec
:
Find km/hr: %2810.2345%2A3600%29%2F1000 = 36.84675 km/hr
:
Convert to mph: 36.84675 * .6214 = 22.897 mph
:
Convert to ft/sec: 10.2354 * 3.28 = 33.572 ft/sec
:
At this speed, how long will it take to run 1.00? One what?
Assume you mean 1 mile
5280%2F33.572 = 157.274 seconds (2 min 37.274) sec to go 1 mile
