An aircraft took off point A(xºN, 15ºE) at 0720h, local time. It flew due West to another point B(xºN, 75ºW) a distance of 5005 km from A.
After a stopover of 1 hour 30 minutes at point B, the aircraft took off and flew for 3 hours 40 minutes due South to a point C. The aircraft maintained an average speed of 910 km/h for the journey from A to B and also from B to C
(Take π = 22/7and the radius of the earth to be 6370 km)
- Calculate the:
- position of point B.
- position of point C
- Determine the local time at point C when the aircraft arrived.
