To calculate the speed of the jogger, we can use the formula:
Speed = Distance / Time
Given that the distance covered by the jogger is 400 meters and the time taken is 90 seconds, we can substitute these values into the formula:
Speed = 400 meters / 90 seconds
Dividing 400 meters by 90 seconds, we get:
Speed = 4.44 meters per second
Therefore, the speed of the jogger is approximately 4.44 meters per second.
