100 yards = 300 feet = 300/5280 = .0568 miles
18 sec = 18/60 minute = 18/3600 hours = .005 hours
thus answer is .0568 miles/.005 hours = 11.36 mph
100 yards in 11 seconds is a pace of 18.6 mph
100 yards/6.7 seconds = 30.5292 miles per hour (rounded)
5.882353.....
It will take you 17.05 seconds to run 100 yards.
100 yards in 10 seconds 20.45 miles per hour.
9.58 seconds in the 100-meter equates to a time of 8.76(8.759952) seconds for 100 yards.
5.3 seconds for 100 yards.
It equates to 9.32688 seconds per 100 yards.
Presuming a continuous speed through the whole 100 meters, someone who ran 100 yards in 10 seconds would take 10.83 seconds to run 100 meters.
It would take: (220/100) times 9.2 = 20.24 seconds
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.
11.9094488 seconds.
