A man walks 1 km towards East and then he turns to South and walks 5 km. Again he turns to East and walks 2 km. After this he turns to North and walks 9 km. Now, how far is he from his starting point?
A walks 10 metres in front and 10 metres to the right. Then every time turning to his left, he walks 5, 15 and 15 metres respectively. How far is he now from his starting point?
Explanation:
Assume start facing North 10 m. Right (East) 10 m. Left (North) 5 m. Left (West) 15 m. Left (South) 15 m. Net: North 10+5−15=0, East 10−15=−5 (5 m West). Distance 5 m.
