Question 17

# Two planes start from the same airport. A flies 50 km East. B flies 15 km North, then turns East and flies 20 km, then turns to its right and flies 15 km. Where is B with respect to A now?

Solution

Let both the planes start from point S. The path of plane A is represented by blue and B's path by black.

Plane A travels 50 km to east and reaches T.

Similarly, plane B travels north for 15 km and reaches R, then flies 20 km towards east and finally stops at P.

Thus, PT = 50 - 20 = 30 km

$$\therefore$$ B is 30 km to the west of A.

=> Ans - (C)
