For a particle in one dimensional motion, the instantaeous speed is always equal to the magnitude of instantaneous velocity. Why ?

Assertion: In general |Displacement| le distance. Reason: The instantaneous speed is equal to the magnitude of the instantaneous velocity,

Which of the following statements is /are correct ? I.Average speed over a finite interval of times is greater or equal to the magnitude of the average velocity. The instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant.

What is instantaneous velocity?

A particle is projected with a speed v and an angle theta to the horizontal. After a time t, the magnitude of the instantaneous velocity is equal to the magnitude of the average velocity from 0 to t. Find t.

In which condition the magnitude of average speed is equal to the magnitude of average velocity?
