A man runs 20 m towards east and turns right, runs 10 m and turns right, runs 9 m and turns left, runs 5 m and turns left, runs 12 m and finally turns left and runs 6 m . Which direction is the man facing ?
Step-by-step Solution:
To solve this, we only need to track the man's direction after each turn. The distances he runs are not relevant to the final direction he is facing.
A faster way is to count the total number of left and right turns. Since one left turn and one right turn cancel each other out, we can find the net effect.
The two right turns cancel out two of the left turns. This leaves a net movement of one left turn from his initial direction.
Final Answer: The man is facing North.
