A man walks 2 Km towards North. Then he turns to East and walks 10 Km....
Steps to solve the problem:
Step 1: Initial Position
- The man starts at a point.
- He walks 2 Km towards North.
Step 2: First Turn
- After walking 2 Km North, the man turns to East and walks 10 Km.
Step 3: Second Turn
- Then, he turns to North and walks 3 Km.
Step 4: Third Turn
- Finally, he turns towards East and walks 2 Km.
Calculation:
- Distance covered towards North: 2 Km + 3 Km = 5 Km
- Distance covered towards East: 10 Km + 2 Km = 12 Km
Using Pythagoras Theorem:
- Distance from the starting point = √(5^2 + 12^2)
- Distance from the starting point = √(25 + 144)
- Distance from the starting point = √169
- Distance from the starting point = 13 Km
Therefore, the man is 13 Km away from the starting point. The correct answer is option B.
