A boat P leaves part A (45⁰N, 50⁰W) and sails at an average speed of 10 knots. It sails due east along a parallel of latitude to B (45⁰N, 42⁰W) and then sails due north to C (48⁰N, 42⁰W). Another boat Q leaves D (55⁰N, 10⁰W) at the same time as P leaves A. It sails due west and then due south to meet boat P at C.
(a) How long does it take boat P to reach point C?
(b) If boat Q sails at the same speed as boat P, how long does the former take to reach point C.
(c) At what speed would boat Q have to sail to reach point C at the same time as boat P.
