315 feet in 9 seconds = about 35 feet per second.
Magnitude of average acceleration = (change of speed) divided by (time for the change)Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2-- That's the average over the 20 seconds. We don't know anything about thevalue of the acceleration at any particular instant during the 20 seconds.-- We're working entirely with scalars ... speed, not velocity, and magnitude ofacceleration ... since we don't know anything about the runner's direction atany time during the whole event.
Depends on the time, average speed = distance / time Usain bolts record time is 9.58 seconds, giving an average speed of: 100 / 9.58 = 10.438 metres per second ( 23.349 mph ) > His maximum speed during the run however, was recorded at 12.22 metres per second ( 27.335 mph )
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
Average speed = 200 meters per 25 seconds It can also be written as 8 meters per second
100 feet in 10 seconds gives an average speed of 10 feet per second.
1 and 5/6m per seconds
The average speed of the runner is 1500m/(180 + 49.67) seconds = 6.531 m/s or 13 knots.
9 hours
Divide the 100 by 13.75 to find the metres per second speed. 100 ÷ 13.75 = 7.27 metres per second.

100 miles/50 seconds= 2 miles per second average speed

Divide 315 by 9. 315 / 9 = 35 fps
About 365.5 meters a minute.
He is running at an average speed of 21.31 mph.
speed = distance/time = 1500/50 = 30 m/s (too fast for a runner, must be a car)
