About 975 yards.
5.3 seconds for 100 yards.
80.25 yards
90 mph = 220 yards in 5 seconds.
1 miles = 1760 yards 1 hour = 3600 s Distance = speed × time = 45 mph × 3 s = 45 miles/hours × 3 seconds = 45 × (1760 yards)/(3600 seconds) × 3 seconds = 45 × 1760/3600 × 3 yards = 66 yards.

5.3 seconds for 100 yards.
speed = distance / time Speed(mph) = (19/1760) / ( 2.5/3600) Division of fractions. speed = 19/1760 X 3600/22.5 Cancel dowm by '10' speed(mph) = 19/176 X 360/2.5 Cancel down by '2' speed = 19/88 x 180/2.5 Cancel down again by '2' speed = 19/44 x 90/2.5 And again speed = 19/22 x 45/2.5 Convert the 2.5 to a fraction 2.5 = 2 1/2 = 5/2 speed = 19/22 X 45 / ( 5/2) becomes speed = 19/22 X 90/5 Cancel down by '5' Speed = 19/22 X 18/1 Cancel down by '2' Speed (mph) = 19/11 X 9/1 Multiply out Speed = 171/11 = 15 6/11 mph or 15.545454.... mph. NB Yes I have made 'heavy weather' of it , but it is done to show methods of calculation, without using a calculator. NNB To compare the faster 100 metre runners in under 10 secs, are only speeding at about 23 mph.
80.25 yards
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.
90 mph = 220 yards in 5 seconds.
28.65 seconds for 50 yards would be the same as 31.33 seconds for 50 meters.
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 yards in 10 seconds 20.45 miles per hour.
To convert 139 yards in 25.75 seconds to miles per hour, first calculate the speed in yards per second. Then convert yards to miles (1 mile = 1760 yards). Finally, convert seconds to hours (1 hour = 3600 seconds). Calculate the speed in miles per hour using the obtained values.
Jason ran 200 yards in 36 seconds
1 miles = 1760 yards 1 hour = 3600 s Distance = speed × time = 45 mph × 3 s = 45 miles/hours × 3 seconds = 45 × (1760 yards)/(3600 seconds) × 3 seconds = 45 × 1760/3600 × 3 yards = 66 yards.
55 meters in 6.47 seconds would be the same as 60 yards in 6.454 seconds.
