40 yards is approximately 36 meters.
If you assume that the first full second is linear acceleration up to top speed, to run 9.55 for 100m you'd accelerate from 0 to 11 meters per second in the first second, then run 11 meters per second from there on.
In the first second you'll cover 5.5 meters. After that, you'll cover 11 meters every second and have 30.5 meters to go, so you'll do that in 2.75 seconds or so.
This will give you a 40 yard dash time, electronically timed from the gun of 3.75 seconds.
HOWEVER, there is one big difference between a football forty and the first 36 meters of a track hundred. The 40 starts when the runner does. This can take off up to a full tenth.
About 10.4 seconds. This is not possible because 100 meters is longer than 100 yards.
========================================================
The correct solution is 8.76
100M = 109.361 yds
set up a proportion as follows:
109.361 yds/9.58 = 100 yds/ x
cross multiply and get:
109.361 x = 9.58 * 100
109.361 x = 958
x = 958/109.361 = 8.7599
Rounded you get 8.76 seconds for 100 yards
3.96s, assuming that you ran at a constant speed the entire time.
A 10.49 100m converts to a 9.592 in the 100-yard dash.
as fast as 4.5 something to 4.7 id think...no definite way to find out though
3.82 seconds
It is 3.88 seconds.
4.6
It would convert to 10.5 seconds for 100 meters.
A time of 1:31 in 600 yards translates to a time of 1:39.5 for 600 meters.
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
1 yard = 0.9144 meters (exactly) 100 yards = 91.44 meters (approximately) Therefore, the speed for a 9.9 second 100 yard dash can be calculated as: Speed = Distance / Time Speed = 91.44 / 9.9 Speed = 9.232 m/s To convert this speed to the 100 meters equivalent time, we can use the formula: Time = Distance / Speed Time = 100 / 9.232 Time = 10.81 seconds (approximately) Therefore, a 9.9 second 100 yard dash is equivalent to a 10.81 second 100 meters race.
3.5735
A 220 yard dash time of 21.80 seconds translates to a time of 21.67 seconds for 200 meters.
11.6 in 100 meters is 4.2 (4.242816) seconds in the 40-yard dash.
10.7 100 meter dash = 9.78 100 yards
4.0 (4.0672512) seconds in the 40-yard dash.
You can't. It would be like extrapolating a marathon time from a mile time.
Roughly 5.04 seconds. .9144 meters to the yard, so call it 91.44 yards. The 40 yards would come out to about 36.58 meters, which goes into the 91.44 right at 2.5 times. 12.6 seconds divided by 2.5 is 5.04 seconds.
11.37 . About 1 1/2 seconds slower than usain bolt
