30 kph or 18.64 mph.
16.39 metres/second
9.09 m/s
Average speed = 200 meters per 25 seconds It can also be written as 8 meters per second
If Usain Bolt runs 100 meters in 10 seconds, his speed is 10 meters per second. Therefore, in 2 seconds, he would cover a distance of 20 meters. This is calculated by multiplying his speed (10 m/s) by the time (2 s). Hence, he runs 20 meters in 2 seconds.
(4 meters/second)(40 seconds) = 160 meters.
To get the speed in such cases, divide the distance by the time. In this case, the answer will be in meters per second.

3 meters per second. enjoy:)
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.
8m/s
21 m/s
Speed = distance/time = 140m/5s = 28m/s
