Question

a body covers 1/3 of its distance with 10 m/ sec velocity and second third of its distance with 20 m/sec of velocity and the last remaining 1/3 with a velocity of 30 m/sec .find the average velocity of the body​

Answer 1

Answer:

your answer is 20 m/sec

Explanation:

Average velocity = sum of variations of velocity/number of variations(n)

                             = 10m/sec + 20 m/sec + 30 m/sec / 3

                             = 60 / 3

                             = 20 m/sec
