a. A ship sails from a place A on the equator along a great circle which makes an angle of 60° with the equator. Find the difference in longitude of A and the place B on the path of the ship where it reaches the latitude 30° N for the first time. (R=6360km). b. A station P is located on the equator, Q and T are two stations at latitude 10 °N, Q being due north of P and T 1062km due east Q. Assuming the earth to be a sphere of radius 6373 km, find the distance PT and its bearing.
