The Kentucky derby was won in 2000 by fusaichi Pegasus in 121 s. If the race is 2011 m, what was his speed?

To find the rate of speed, simply divide the length of the race by the length of time it took for the horse to run the race. In this case, 2011 m / 121 sec = 16.619 m/sec. Converting this from m/sec to mph, the value becomes approximately 37.1778, or 37.18 mph.
