The motorcycle's average velocity will be 20 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the average velocity.
What is average velocity?
The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.
V= 72km/hr =20 m/sec
Total distance travelled by the motorcycle;
D= v ×t
D=(20 m/sec)×20 sec
D=400 m
The average velocity is:
[tex]\rm v_{avg}=\frac{d_{total}}{t_{total}} \\\\ \rm v_{avg}=\frac{400}{20} \\\\ v_{avg}=20 m/sec[/tex]
Hence,the motorcycle’s average velocity will be 20 m/sec.
