A runner completes a 400 m lap in 50 seconds. What is the average speed of the runner in m/s? (2019)

Step 1: Identify the total distance the runner completed, which is 400 meters.
Step 2: Identify the total time it took the runner to complete the lap, which is 50 seconds.
Step 3: Use the formula for average speed, which is Average Speed = Total Distance / Total Time.
Step 4: Plug in the values: Average Speed = 400 meters / 50 seconds.
Step 5: Calculate the average speed: 400 divided by 50 equals 8.
Step 6: Conclude that the average speed of the runner is 8 meters per second (m/s).

Average Speed – Average speed is calculated by dividing the total distance traveled by the total time taken.
