Ramesh takes 50 seconds to walk from one end to the other end and back on 25 m long road. Class 9

Question 1.

Ramesh takes 50 seconds to walk from one end to the other end and back on 25 m long road. Find the average speed and average velocity within the time interval of 50 s. Class 9

Answer:

Total distance travelled in 50 s = 25 + 25 = 50 m

Total displacement travelled in 50 s = 0 m

Average speed = [latex]\frac{\text { total distance travelled }}{\text { time interval }}[/latex] = 50/50 = 1 m/s

Average velocity = [latex]\frac{\text { displacement }}{\text { time interval }}[/latex] = 0
