Their speed is ten yards per second.
Takamo added: There are several variables with in this question. We have to determine how fast a person can cover 40 yards. In this case, it's 4 seconds. To determine the actual speed, as in Miles Per Hour, (MPH) we have to use a known constant. Say, a car going 60 MPH. We all know that a car going 60 MPH is traveling at one mile per minute. There are 60 seconds in a minute, and 5280 feet in a mile, so by dividing the 5280 feetby 60 seconds, we find that the car is traveling at a velocity of 88 FPS(feet per second).
A human can run, in this case, 40 yards in 4 seconds. There is 120 feet in 40 yards, so the runner moves at a velocity of 30 FPS. To match the un-known, (the MPH of the runner) and compare it to a known MPH, (the car) we divide the FPS of the car by the FPS of the runner and we get 2.6. This is the variable between them, in that the same distance, the car is traveling 2.6 times faster than the runner. Knowing the speed of the car, 60 MPH, and knowing now, how much faster its going than the runner, we simply divide the MPH of the car, 60MPH by 2.6 and we get the runner's land speed of of 23.07 MPH.

How many miles per hour is running 100 yards in 9.7 sec?
To do this you need to know:60 second in a minute60 minutes in an hour1760 yards in one mileNow first work out how far one would travel running at that speed in one minute, by finding how far you would have traveled in one second-100/9.7 = 10.30927835051546 yards /secondThen multiply by 60 to get distance traveled in one minute =10.30927835051546 * 60 = 618.5567010309278 yards / minute.Now multiply by 60 again to get the distance traveled in an hour618.5567010309278*60=37113.40206185567 yards / hourOK we now know that we would be running at a speed of 37113.40206185567 yards an hour. BUT we want the answer in miles an hour, so we have to divide this by the number of yards in a mile:37113.40206185567/1760=21.09 miles per hour.Compare this with the related answer for this question where the distance run was in Meters (which are longer than yards - so you would be running faster)
