Question

A boy takes 15 minutes to go from his house to school and 10 minutes for return journey. Distance between school and house is 4 Km. Calculate average speed and average velocity.​

Answer 1

Answer:

average speed=19.2km/hr

average velocity=0km/hr

Reason:

total distance covered=8km

total time taken=25 minutes

therefore distance travelled in 1 hour(60min=25×2.4)= 8×2.4=19.2 in one hour

therefore average speed=19.2

Now,

As total displacement from going

to school and return=0

implies average velocity=0.
