Answer :
The motorcycle's average velocity will be 6 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.
Total distance travelled by the motorcycle;
d=20 m+10 m
d=30 m
The average velocity is found as;
[tex]\rm v_{avg}=\frac{d}{t} \\\\ \rm v_{avg}=\frac{30}{5} \\\\ v_{avg}= 6 \ m /sec[/tex]
Hence,the motorcycle’s average velocity will be 6 m/sec.
