A man walks 2 km towards East and then he turns to South and walks 6 km. Again he turns to East and walks 4 km, after this he turns to North and walk 14 km. How far is he from his starting point?

Solution

Correct Option: 1

Net East movement = 2 + 4 = 6 km.

Net North movement = 14 - 6 = 8 km.

Distance from start = 62+82=36+64=100=10\sqrt{6^2 + 8^2} = \sqrt{36 + 64} = \sqrt{100} = 10 km.
