Usually average speed means the rationof total distace travelled to the total time elapsed. However, sometimes thephrase ` average speed can vean the magnitude of the average velocity. Are the two same ? Discuss.

Explanation

It is not correct to say that the average speed of the body is ewual to the magnitude of the average velocity because they have got dufferbt meanings. As average sped, v_(av)= total distance travelled//time taken and magnitude of average velocity `= | vec v_(av) | =| displacement//time |`. As, the distance travelled by a moving body is always positive and can never be zero or negative , whereas the displacement of body can be wero, negative or positiove. So, distance `ge` displacenent. gtbrgt Hence, ` v_(av) ge | vec v_(av) |` .
