Question

Mohan takes 15 minutes to go from his own to school and 30 minutes for the return journey if the distance between the school and the home is 4.5 km what is the average velocity​

Answer 1

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 ✔

Answer 2

Answer:

1080 m / sec
