1 miles = 5280/3 yards = 1760 yards. 50 yards / 1760 yards/mile ~= 0.02841 miles 7.2 seconds / 3600 seconds/hour ~= 0.002 hours 0.02841 miles / 0.001833 hours ~= 14.2 miles per hour In general divide 102.27 by your time in seconds to get mph.
The sprinter runs 22.5 miles per hour. The sprinter covers 110 yards in 10 seconds. That's 110 yards per 10 seconds. (It's also 11 yards per second.) We need to convert the 110 yards/10 seconds into miles per (one) hour, or miles/hour. So let's do it. Here are the conversion factors: 1 mile = 1760 yards 1 minute = 60 seconds 1 hour = 60 minutes (11 yd/sec)(60 sec/min)(60 min/hr)(mile/1760 yd) = 11 x 60 x 60 x 1/1760 = 22.5 miles/hour
About 163 mph
This question cannot be answered for lack of information.
5.3 seconds for 100 yards.
23.243822 miles per hour
198 yards in 3.4 seconds
40 yards in 4 seconds
200 meters in 27.6 seconds equates to 16.21 miles per hour.
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.
