Understanding the Movement of the Child
To find how far the child met his father from the starting point, we can break down the movements step by step.
Initial Movement
- The child starts at a point (let's call it Point A) and moves 90 m East.
- This brings him to Point B.
Right Turn and Movement
- From Point B, he turns right (now facing South) and moves 20 m.
- He arrives at Point C.
Another Right Turn and Movement
- From Point C, he turns right again (now facing West) and travels 30 m.
- Now he reaches Point D (his uncle's house).
Final Movement to Meet Father
- From Point D, he moves 100 m North to meet his father at Point E.
Calculating Distance from Starting Point
1. Coordinates of Points:
- Point A (0, 0)
- Point B (90, 0)
- Point C (90, -20)
- Point D (60, -20)
- Point E (60, 80)
2. Distance Calculation:
- The coordinates of Point E (where he meets his father) are (60, 80).
- Using the distance formula, the distance from Point A to Point E is calculated as:
- √[(60 - 0)² + (80 - 0)²] = √(3600 + 6400) = √10000 = 100 m.
Conclusion
The child meets his father 100 metres away from the starting point, confirming the answer is option 'B'.
