Answer:
Total time = 15 + 30 = 45 minutes. 45 minutes = 45 × 60 = 2700 seconds. Total distance =4.5 + 4.5 = 9 km because he travels once to school and again covers the same distance while returning

Answer:
Working formula:-
●Average Velocity = Total distance/Total time.
Given:-
Total time = 15 + 30 = 45 minutes.
45 minutes = 45 × 60 = 2700 seconds.
Total distance =4.5 + 4.5 = 9 km because he travels once to school and again covers the same distance while returning.
9 km = 2.5 m/s
Applying the working formula:-
●Average Velocity = 2700/ 2.5 m per sec sq. = 1080 m per sec sq ✔
