Answer:
The average velocity of the motor cycle in m/s = 20 m/s
Explanation:
Given;
average velocity of the motor cycle, v = 72 km/h
time of motion, t = 20 s
The average velocity is already given in the question, the time in the question is irrelevant.
You can also convert the 72 km/h to m/s by dividing by 3.6 km/h
Thus, 72 km/h divided by 3.6 km/h = 72 / 3.6 = 20 m/s
Therefore, the average velocity of the motor cycle in m/s = 20 m/s
