See question in image and show workings Note : 1 nautical mile = 1.86km

ycow [4]

Answer:

AB is on the latitude 30°N.

Find AB:

AB = 2*3.142*6400*cos 30°*(32+35)/360 = 6482.15 km

BC is along longitude 35°W

Find BC:

BC = 2*3.142*6400*(30 + 20)/360 = 5585.77 km

Total distance traveled:

6482.15 + 5585.77 = 12067.92 km

Convert the distance to nautical miles:

12067.92/1.86 = 6488.13 nautical miles

Find the average speed:

6488.13/22 = 294.92 nautical miles / hour

Note. This is unrealistically high speed for a ship, this must be a plane or the time given wrong.
