A man faces North and covers 7 kilometers, turns west and covers 2 kilometers then turns South and covers 4 kilometers and turns West again and covers 2 kilometers. How far is he from the starting
- 4 kilometers
- 5 kilometers
- 7 kilometers
- None of above
Explanation
. Starts facing North, moves 7 km North.
2. Turns West, moves 2 km.
3. Turns South, moves 4 km → Now he's (7 - 4) = 3 km North from start.
4. Turns West again, moves another 2 km → Total 4 km West.
So, from starting point, he's 3 km North and 4 km West.
Use Pythagoras theorem to find distance from start:
Distance = √(3² + 4²) = √(9 + 16) = √25 = 5 km
