The speed is exactly 350/17 yards per second, or roughly 42.1 miles per hour.
90 mph = 220 yards in 5 seconds.
None. 2.5 seconds is a period of time. It is not a speed since there is no measure of distance involved. By contrast, yards per minte is a measure of speed. The two measures are incompatible.
1 miles = 1760 yards 1 hour = 3600 s Distance = speed × time = 45 mph × 3 s = 45 miles/hours × 3 seconds = 45 × (1760 yards)/(3600 seconds) × 3 seconds = 45 × 1760/3600 × 3 yards = 66 yards.
30 yards per second, or 90 feet per second.
There are 1760 yards in one mile. Therefore, 40 miles per hour is equal to 40 x 1760 = 70400 yards per hour. There are 3600 seconds in one hour. Therefore, 70400 yards per hour is equal to 70400/3600 = 19.5 recurring (that is, 19.5555..) yards per second.
90 mph = 220 yards in 5 seconds.

It will take you 17.05 seconds to run 100 yards.
100 yards in 10 seconds 20.45 miles per hour.
None. 2.5 seconds is a period of time. It is not a speed since there is no measure of distance involved. By contrast, yards per minte is a measure of speed. The two measures are incompatible.
You cannot know this without knowing the speed travelled at
4.86 seconds.
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.
1 miles = 1760 yards 1 hour = 3600 s Distance = speed × time = 45 mph × 3 s = 45 miles/hours × 3 seconds = 45 × (1760 yards)/(3600 seconds) × 3 seconds = 45 × 1760/3600 × 3 yards = 66 yards.
30 yards per second, or 90 feet per second.
There are 1760 yards in one mile. Therefore, 40 miles per hour is equal to 40 x 1760 = 70400 yards per hour. There are 3600 seconds in one hour. Therefore, 70400 yards per hour is equal to 70400/3600 = 19.5 recurring (that is, 19.5555..) yards per second.
About 8.18 seconds, based on a statute mile of 5280 feet.
