The formulae for fiding speed is:
Speed= Distance traveled / time taken
So: 100m/10s (100 divided by 10)
So: 10m/s (meter per second)

To calculate average speed, you would use the formula: average speed = total distance / total time. In this case, the total distance is 100 meters and the total time is 55 seconds. Therefore, the average speed would be 100 meters / 55 seconds = 1.82 meters per second.
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.
6.25 meters per second
100 meters in 9.77 seconds equates to an average speed of 22.9 mph
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
