Use these numbers: 1 meter = 3.28084 feet 1 mile = 5,280 feet 1 hour = 3,600 seconds (100 m / 14.9 sec) x (3.28084 ft / m) x (1 mi / 5,280 ft) x (3,600 sec / hr) = (100 x 3.28084 x 3,600 m - ft - mi - sec) / (14.9 x 5,280 sec - m - ft - hr) = 1,181,102.4 / 78,672 = 15.013 mi/hr (rounded) Reality Check: This doesn't seem too spectacular. 15 mph is exactly 4 minutes per mile. You'd think that a decent runner could do better than that for a 100-m sprint.
To convert meters per second to miles per hour, you need to multiply the speed in meters per second by 2.237. Therefore, if you run a 100-meter race in 14.9 seconds, you are going approximately 15.87 miles per hour.
You are running 23.31 miles per hour.
You have averaged 36.5 miles per hour. You are probably going quite a bit faster than that at the end.
