Question

An athlete runs 600 m in 2 minutes and the next 1000 m in 1 minute on the same straight
path. What is his average speed and average velocity?​

Answer 1

Answer:

Average speed =533.34 m/minute= 8.89 m/s = Average velocity

Explanation:

As in the both cases the direction is same i.e. on the same straight line so in both cases the total displacement is added .

Therefore, Average speed = total displacement/ total time = {S(1) + S(2)}÷ {t(1) + t(2)} = Average velocity

= 1600 m ÷ 3 minutes

= 533.34 m/minute

= 8.89 m/s
