A man moves 4 m. towards east then 3 m. towards left after then 8 m. towards right then 6 m. towards right then 16 m. towards right. Finally he moves 4m towards north followed by 6 m. towards right. What is his distance from the starting point.
OPtion
1) 9 m.
2) 8 m.
3) 7 m.
4) 6 m.
5) 5 m.
6) 4 m.
7) 3 m.
8) 2 m.
9) 1 m.
10)None of these
Solution
Use a graph to obtain the result.
Distance = √(1^2+2^2)
=> √5.
Option 10)
