Average speed = distance/time = 20 metres per second.
100m in 20s = 300m in 60s = 1 minute so 300m x 60min = 18000m in 1hour Answer: 18 kilometres per hour
sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
It is an average speed of 10 metres per second or 22.4 miles per hour.
Its average speed is exactly 100 meters per 25 seconds. Its unit speed is 4 meters per second.
speed = distance/time = 100m / 50s = 2 m/s
The average speed of the world record in the 100m dash is around 37.58 km/h (23.35 mph).
Average speed = distance/time = 20 metres per second.
100m in 20s = 300m in 60s = 1 minute so 300m x 60min = 18000m in 1hour Answer: 18 kilometres per hour
Here's some quick math... Might be wrong: 9.69 seconds is the record in a 100M race 328.08 feet = 100 M 33.86ft/sec for 100M converted to mph... 23.08mph average speed.

by speed training. most common way is to sprint for 100m jog for next 100m sprint another 100m jog 100m. do this continously for 30mins. do it at least 3 times a week. your speed will improve. maybe not significantly but it will improve.

Could you be more specific? There's a photon, which travels at the speed of light...there's a tachyon that travels faster than the speed of light, but backwards in time...there's the cheetah (65mph)...there's the peregrine falcon (200mph in a dive)...there's Usain Bolt who can run 100m in 9.58 seconds...
Approx. 50 seconds
It approximately travels from 10-100m
18m/s
