Understanding the Child's Journey
The child's journey can be broken down into clear steps to determine the distance he met his father from the starting point.
Step 1: Initial Movement
- The child starts at the origin (0,0) and moves 90 metres East.
- New position: (90, 0)
Step 2: First Right Turn
- He turns right (now facing South) and moves 20 metres.
- New position: (90, -20)
Step 3: Second Right Turn
- Another right turn (now facing West) and he moves 30 metres to his uncle's place.
- New position: (60, -20)
Step 4: Final Movement
- From his uncle's place, he moves 100 metres North.
- New position: (60, 80)
Calculating the Distance from Starting Point
- To find the distance from the starting point (0, 0) to the final position (60, 80), we can use the distance formula:
Distance = √[(x2 - x1)² + (y2 - y1)²]
- Here, (x1, y1) = (0, 0) and (x2, y2) = (60, 80).
- Distance = √[(60 - 0)² + (80 - 0)²]
- Distance = √[3600 + 6400]
- Distance = √10000
- Distance = 100 metres
Conclusion
The child met his father 100 metres from the starting point, confirming that the correct answer is option 'B'.
