Question

Why us te speed of rotation greater at the equator than the arctic circle?

Answer 1

the speed of any object is directly proportional to the distance traveled so the speed of equator is greater than any of the latitude on earth because earth revolve at the fix rate of time so the time is fixed for every latitude so it totally dependent on the distance of latitude or you can say that the length of latitude so equator is the longest latitude so it travels faster than any one
