The Earth spins on its axis once every every 24 hours or 8.64 x 104 s?

Question

The speed of a person standing at the equator relative to a person standing at the North Pole is
(a) 0 m/s (b) 385 m/s (c) 464 m/s (d) 928 m/s (e) 1253 m/s
(Note that 1 m/s = 2.2 miles per hour)

Answer 1

Equatorial radius:6378 km = 6.378x10^6 m.
The speed of a person standing at the equator is:
2*pi*6.378x10^6 m/ (24*3600s) = 463.8 m/s
Earth spin would not move the person standing at the North Pole. Thus the correct answer is (c).

Answer 2

Do you mean miles per second?
