Suppose a runner completes one lap around a 400-m track in a time of 50 s. Calculate the average speed of the runner.

please explain process

To calculate the average speed of the runner, we can use the formula for speed, which is defined as distance divided by time. In this case, the distance is one lap around the track, which is 400 meters, and the time taken is 50 seconds.

Step 1: Write down the given values:
Distance = 400 meters
Time = 50 seconds

Step 2: Use the formula for speed:
Speed = Distance / Time

Step 3: Plug in the given values into the formula:
Speed = 400 meters / 50 seconds

Step 4: Calculate the average speed:
Speed = 8 meters per second

So, the average speed of the runner is 8 meters per second.

To calculate the average speed of the runner, we need to divide the total distance covered by the runner by the total time taken. In this case, the runner completes one lap around a 400-meter track in a time of 50 seconds.

To calculate the average speed, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the total distance covered by the runner is 400 meters, and the total time taken is 50 seconds. Plugging in these values into the formula, we get:

Average Speed = 400 meters / 50 seconds

Now, we can simply perform the calculation:

Average Speed = 8 meters per second

So, the average speed of the runner is 8 meters per second.

400 m/50 s = 8 m/s
