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.

How many mph can a person run with a 27 sec on a 220?
To calculate the speed in mph, we first convert the time to minutes: 27 sec is 0.45 minutes (27/60). Then we divide the distance (220 yards) by the time in hours: 220 yards / (0.45 minutes * 60 min/hr), which equals approximately 293.33 yards per hour. Converting yards to miles (1 mile = 1760 yards) gives us a speed of about 6.62 mph.
300 yards in 15 seconds what is the mph?
