1 meter = 1.0936133 yards 40 meters x 1.0936133 = 43.744 yardsSo 40 meters is roughly 43.7 yardsSay you ran a 5.10 40 meter sprint then you would do this:40/43.7 = .9153.9153 x 5.10 = 4.66So by running a 5.10 40 meter you ran about a 4.66 40 yard dashThere 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 meters10m- 3.4235136m = 6.5764864mAs it is in value of ten, it is an easy conversion to 65.764864%0.65764864 x .957sec = 0.62936974848 sec5.10 seconds - .957 seconds = 4.143 seconds4.143sec + 0.62936974848 sec = 4.77 seconds
