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.
100 yards west
There are 3600 seconds in one hour. Therefore, 100 yards per second is equal to 100 x 3600 = 360000 yards per hour. There are 1760 yards in one mile. Therefore, 360000 yards per hour is equal to 360000/1760 = 204.54 recurring (that is, 204.545454...) miles per hour.
