An aircraft is fl

Answer :

The figure is given below:



Let aircraft fly at a constant height of y km


and let the distance from a point to the starting point of jet bet x km.


Thus, BD = EC = y km


And, AB = x km


As distance = speed × time.


Distance taken by craft to travel from D to E


Using Trigonometry;


DAB = 45°


EAC = 30°


BC = AC – AB = 2 km





= 2.732 km
