we know that speed=distance/time
a point at the equator has the larger distance to move in one revolution where as the point at arctic will have less distance to cover one solution.
Since the speed is directly proportion to distance keeping time constant
the point at equator covers greater distance with greater speed.

Velocity = angular speed×radius
Here,distance from axis of rotation is maximum at the equator,so velocity is maximum
At Arctic circle, distance from axis is smaller
So speed is lower
