The ratio fo the total displacment of a body to the total time taken is __________

The ratio of the total distance travelled by a body to the total time taken is known as its _________

A body cover 20 m in 2 s and another 20 m in next 4s. Arrange the following steps in sequential order to find th average velocity of the body . (A) Find the displacements of the body in first 2s and next 4 s from the given data. (B) find the displacements of the body . (C) find the total time taken by the body to complete the total displacement . (D) Use the formula, average velocity = ("total displacement")/(" Total time taken")
