### Why Is the magnitude of instantaneous velocity always equal to the instantaneous speed?

Because speed is the magnitude of the velocity vector. The
velocity consists of the speed and the direction, and the whole
thing can be embodied in a 3D vector.
If you like the velocity is the magnitude (the speed), which is
a scalar (just a real number), multiplied by a unit vector in the
right direction.

### Instantaneous speed at an instant is equal to magnitude of instantaneous velocity at that instant Why is it so?

Instantaneous velocity mean change of displacement in extremely
small amount time. (in math way, taking[ lim t--->0 (change in
displacements/change in time) ]. instantaneous speed is the same
expect displacement change to distance. So,because of very very
small change in time, magnitude of distance and displacement will
be same for any direction the object is moving.
