A plane leaves Karachi at 1530 to fly to Bangkok.  The distance is 3840 km.  The plane flies at an average speed of 720 km/h.  The local time in Bangkok is 2 hours ahead of the local time in Karachi.  Find the local time in Bangkok when the plane arrives.​

Since Bankok is 2 hours ahead Karachi, then it left Karachi at 1530 + 2 =1730 Bankok time.


3840 / 720 = 5 1/3 or 5 hours and 20 minutes it took the airplane to fly to Bankok.


So, 1730 + 520 =2250 or 2250 - 1200 =10:50 pm Bankok time when the plane arrived.
