Calculating Average Speed in a 200m Race

Amal's Average speed: 9 m/s

Final answer:

Kamal's average speed during the 200m race was 8.55 ms^-1. In the given problem, Amal finishes the race when Kamal is still 10 meters behind. This means Kamal ran only 190 meters (200m - 10m) by the time.

Explanation:

Amal finished the race.

Given that Amal's average speed was 9 ms^-1, we can calculate the time it took for Amal to finish the race by using the formula for time which is distance divided by speed.

Therefore, the time taken is 200m/9ms^-1 = 22.22 seconds.

Since Kamal was also running for the same amount of time, we can now find Kamal's average speed.

Using the speed formula (Speed = Distance / Time), Kamal's average speed was 190m / 22.22s = 8.55 ms^-1.

In a 200 m race, Amal beats Kamal by 10 m. If Amal's average speed was 9 ms-1, what was Kamal's average speed?

Kamal's average speed during the 200m race was 8.55 m/s. In this scenario, Amal finishes the race ahead of Kamal by a distance of 10 meters. Therefore, Amal has completed the race while Kamal has only run 190 meters. By using the formula Speed = Distance / Time, we can calculate Kamal's average speed to be 8.55 m/s.
