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.
A reliable way to convert a hand-held 100-yard time to an electronic 100-meter time is to multiply the hh-time by 1.103. Therefore, 10.2 in the 100-yard dash time equates to an 11.25 100-meter dash time. Also, to convert an electronic 100-yard dash time to an electronic 100-meter dash time, multiply the first time by 1.088. For example, a 10.20 electronic 100-yard time equates to an 11.10 electronic 100-meter dash time.

Jesse Owens' sprint distances were the 100 yard and 100 meter dash, the 220 yard and 200 meter dash, and the 4 x 110 yard (college) and 4 x 100 meter relays.
At a constant speed it would be 4.36, but in reality your speed would change and you have to start at being stationary and so would be accelerating at 40 yards, so it is not a definitive answer.
You can't. It would be like extrapolating a marathon time from a mile time.
