Two towns A and B are 960km apart with A to the west of B. On each of two days, a plane travels directly from A to B and back to A.
(a) On the first day, there is a wind of 90km/h blowing from the north. Given that the speed of the plane in still air is 410km/h, find
(i) the course set by the pilot for the journey from A to B
(ii) the course set by the pilot for the return journey from B to A
(iii) the total time taken for the two journeys
*I have draw the diagram and entered the necessary information on the diagram but I just couldn't get an angle inside the triangle. Please help. Any help will be greatly appreciated*
