1 meter = 1.0936133 yards 40 meters x 1.0936133 = 43.744 yards
So 40 meters is roughly 43.7 yards
Say you ran a 5.10 40 meter sprint then you would do this:
40/43.7 = .9153
.9153 x 5.10 = 4.66
So by running a 5.10 40 meter you ran about a 4.66 40 yard dash
There is a fundamental flaw in this. The start and the first thirty meters should not be included in the percentage because that is slower. The last 10 meter segment should be the only part adjusted. Using the seven fastest 100m sprinters over the past twenty years, their 30-40 meter segment is 18.76% of their overall 40 meter split. So the 18.76% of a 5.10 meter time would be .957.
The extra 3.744 yards = 3.4235136 meters
10m- 3.4235136m = 6.5764864m
As it is in value of ten, it is an easy conversion to 65.764864%
0.65764864 x .957sec = 0.62936974848 sec
5.10 seconds - .957 seconds = 4.143 seconds
4.143sec + 0.62936974848 sec = 4.77 seconds
50 yards = 45.72 metres.
So to convert 50 yards time to 50 metres, multiply the 50 yd time by 50/45.72 or by 1.0936
(55m time / 1.09361) * .7272
You divide it
His 5.0 40-meter dash translates to a time of 4.572 seconds in the 40-yard dash.
A 12.5-second 100m equates to a time of 4.572 seconds in the 40-yard dash.
The projected time would be 4.206 seconds for the 40-yard.
You can't. It would be like extrapolating a marathon time from a mile time.
1 yard = 0.9144 meter meter to yard conversion formula: x meters / 0.9144 = 40 meters / 0.9144 = 43.744 yards
40 yard dash/10 yard dash= 4 What ever the time you got for the ten yard, you multiple it by 4. It could be an average of your running time per 10 yard dash. Sometimes for several runners, they would feel worn out by the time when reaching the 40 yard mark.
To convert a hand-timed (1/10 of a second) 100-yard time to and auto-timed (1/100 of a second) 100-meter time, multiply the hand-time by 1.082. To convert an auto-timed 100y to an auto-timed 100m time, use 1.11.
Mathematically calculated Rose' 40 yard time is 4.48.This was calculated by taken Chris Johnson's 20 yard time and Derrick Rose' 20 yard time of 2.65 in which i got from http://www.muscleprodigy.com/derrick-rose-workout-arcl-1189.html and subtracting the two times and I accumulated 0.24 I added 0.24 to Chris Johnson's 40-yard time and that equaled 4.48.
40 Square Metres
Eli Manning's 40-yard dash time is 4.92.
Multiply each by 0.9144 1 yard = 0.9144 meter
