1 mile = 1760 yards 1/1760 mile = 1 yard 100/1760 miles = 100 yards 1 hour = 3600 seconds 1/3600 hour = 1 second 9.21/3600 hours = 9.21seconds speed = distance / time = (100/1760 miles) / (9.21/3600 hours) ~= 22.21 mph.
12.7841mph
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
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.
90 mph = 220 yards in 5 seconds.
To find out how many mph is 100 yards in 11 seconds: First, convert 100 yards to miles (100 yards = 0.057 miles). Next, calculate the speed by dividing the distance (in miles) by the time (in hours) - 0.057 miles / (11 seconds / 3600 seconds) = 19.64 mph.
He is running at an average speed of 21.31 mph.

40.9 seconds.
100 kph = 62.1 mph
At 4 mph, you would cover 88 yards in one minute. In 45 seconds, you would cover 66 yards (88 multiplied by 0.75).
100 mph = 160.9 kph
0.00057 hours approx = 0.034 minutes or 2.05 seconds.
