To calculate the average velocity of a motorcycle, you need to divide the total displacement by the total time taken. In this case, the displacement is the distance traveled, which is 2.4 km, and the time taken is 5 minutes.
First, let's convert the time from minutes to hours to match the distance unit (kilometers). There are 60 minutes in an hour, so 5 minutes is equal to 5/60 = 1/12 hours.
Average velocity = Displacement / Time
Average velocity = 2.4 km / (1/12 hours)
To divide by a fraction, we can multiply by its reciprocal:
Average velocity = 2.4 km * (12/1 hours)
Average velocity = 2.4 km * 12 hours
Average velocity = 28.8 km/h
Therefore, the average velocity of the motorcycle is 28.8 km/h.
