The distance between New York City and London is 3470 mi.
(a) If a radio wave from New York City is transmitted directly across the ocean, how long will it take to reach a receiver in London?
(b) In fact, due to the curvature of the earth, radio waves cannot be transmitted directly across such large distances on the earth. Instead, a signal is typically transmitted to a communications satellite located 2.20 x 104 mi above the surface of the earth. If the satellite is located midway between the two cities, how long will the radio wave take to reach London. (Disregard the effect that the curvature of the earth has on the calculations.)
