Running Times

At age 10, the average boy doesn't run much faster than the average girl. The girl completes a 50-yard dash in 8.9 seconds while 10-year-old-males run the same distance in 8.6 seconds. But by age 17, the difference is larger with females running the same distance in 8.2 seconds while males complete the 50-yard dash in an average of 6.7 seconds.
