A man goes 10 km westward, then turns right and proceeds 4 km, then travels 10 km towards left, then travels 8 km towards left and finally goes 4 km northward. Calculate his distance from his initial place in the horizontal direction.
Let the man starts from point A and goes 10 km westward to point B, then turns right and proceeds 4 km northwards towards C, then travels 10 km towards left, then travels 8 km towards left to reach E and finally goes 4 km northward to stop at point F.
$$\therefore$$ His distance from his initial place in the horizontal direction = AF = AB + BF
= $$10+10=20$$ km
=> Ans - (A)
