Given information:
- Nishu starts from a fixed point.
- He goes 15 km towards North.
- After turning to his right, he goes 15 km.
- Then, he goes 10, 15 and 15 metres after turning to his left each time.
To find: How far is he from his starting point?
Solution:
Let's represent Nishu's movements on a diagram:
N
|
|
W ----C---- E
|
|
S
- Nishu starts at point C.
- He goes 15 km towards North and reaches point W.
- He turns right and goes 15 km towards East, reaching point E.
- He turns left and goes 10 metres towards North, reaching point F.
- He turns left again and goes 15 metres towards West, reaching point G.
- Finally, he turns left once more and goes 15 metres towards South, reaching point H.
We need to find the distance between points C and H, which is the straight line distance or the hypotenuse of the right-angled triangle CHG.
Using Pythagoras theorem, we can calculate the hypotenuse CH as follows:
CH² = CG² + GH²
CG = CF + FG = 15 + 15 = 30 m
GH = HG = 15 m
CH² = 30² + 15²
CH² = 900 + 225
CH² = 1125
CH ≈ 33.54 m
Therefore, Nishu is approximately 33.54 m away from his starting point.
Answer: Option (b) 10 metres.
