Question 42
A flock of migrating geese flies 20 km East, then turns South and flies 50 km, then turns East and flies 40 km, and turns to its left and flies 50 km. Where is the flock now with reference to its starting position?
Solution
Let the flock of migrating geese starts from point A and flies 20 km East to reach B, then turns South and flies 50 km to point C, then turns East and flies 40 km to reach point D, and turns to its left and flies 50 km northwards finally to stop at point E.
=> AE = $$20+40=60$$ km
$$\therefore$$ The flock is now 60 km east with reference to its starting position.
=> Ans - (B)
