The answer depends on which 40-yard line. If you're on your own twenty and run to your own 40, you ran twenty yards. If you start from your own twenty and run to your opponent's 40, you ran forty yards.
40 yards. 15 to midfield is 35 yards (50 - 15 = 35) midfield to opposing 45 is 5 yards (50 - 45 = 5)

From his own 15 yard line to midfield (the 50 yard line) is 50 - 15, or 35 yards. From midfield to the opposing team's 45 yard line is 50 - 45, or another 5 yards. He has advanced the ball 40 yards for scoring purposes. However, if he zig-zagged, or ran diagonally across the field to do so, he would have run much further.
100 + 440 + (1760/4) = 980 He therefore ran 980 yards.

Your time in the 40 would be 10.4 seconds.
(50 yards/6.6 seconds) x (3,600 seconds/hour) / (1,760 yards/mile) = 15.496 miles per hour (rounded)
3 feet equal 1 yard so do 1760 x 3 and that would be 5280 feet ran
3,520 yards
Looking at the video, Dorsett ran for 99 1/3 yards, but adding the run to the sideline he actually ran for 126 yards exactly since a football field is 53 1/3 yards wide. Half it, add it up and you have your answer bud.
10 yards. He ran 5 yards first, then 3 yards, then, even though he lost two yards, he still ran 2 yards. So he ran for a total of 10 yards.
