2. Economics of Flying : ( K6, A6, T 4, C3 Marks) A plane has to fly from city A to city B. City B is located at distance of 900 km from city A in the direction of bearing of 650. There is a wind flowing from N 30 W with a magnitude of 40 Km/h. Plane can fly at 600 Km/h. in still air. There is not enough demand to fly from A to B directly. There are two options. Options are going through one of the cities C and D. In both options, flight stops at C or D for one hour. Option 1: Stop at C Option 2: Stop at D Location of C: 400 km from A | Location of D: 300 km from A at bearing of 350 at bearing of 1250 a) Calculate the ground speed for both situations. Remember there are two legs of journey for both options. b) There are 5 crew members on a flight. On average it costs $60/h for each crew member. Calculate the cost for the crew for both options. Round the time of flying to the nearest minute
