5.3 seconds for 100 yards.
Assuming the same average rate of travel, since 100 yards is 0.9144 times the size of 100 metres, 10.8 seconds for 100 metres would correspond to 10.8 x 0.9144 = 9.87552 seconds for the 100 yards.
60 yards is equivalent to about 55metres, so it will be a little bit below 6.9 maybe?
Your time would be just about the same since a yard is 36 inches and a meter is 39.37 inches. 100 yards is 91.44m. With a time of 11.5 for about 90m, you are running on average 10m in about 1.28 seconds, making your 100m time about 12.78, given the same circumstances.
23.243822 miles per hour
10 metres in 5 seconds or 2 metres per second.
198 yards in 3.4 seconds
40 yards in 4 seconds
1000 meters in 60.6 seconds = 36.91 mph
900 meters/30 seconds = 30 meters/second
10 seconds
My guess would be around 7 or 7.5 which would be about 8.5 in the 100 meters cause 100 meters is 110 yards and grizzly bears can run about 30 to 33 mph but the thing that would slow them down is that in 100 yards you need a good start a bear needs to get going to reach that speed soo from a dead start again I'm just guessing not sure but I'm guessing 100 yards Maby 8 seconds in the 100 meters about 9 or 8.8 secounds but onece they get going no way in hell your getting away from one
