The winner of the foot race in the first recorded Olympics in 776 BC was Coroebus of Elis. He won the stadion, a sprinting event that was about 192 meters long.

25,00000 square foot
Distance divided by the time it takes to cover the distance, equals average speed per unit of time. For example: An object takes 0.5 seconds to cover 1 foot. 1 divided by 0.5 equals 2 (1/0.5=2) so it is traveling at an average speed of 2 feet per second.
Eight-Foot High Speed Tunnel was created in 1936.
About 200 metres.
