To solve this problem, let's break down the movements of the child step by step:
1. East: The child goes 90 m in the east to look for his father.
2. Right Turn: The child turns right and goes 20 m.
3. Right Turn: The child turns right again and goes 30 m to reach his uncle's house.
4. North: From the uncle's house, the child goes 100 m to the north and meets his father.
Now let's calculate the distance between the starting point and where the child meets his father:
1. East Movement: The child goes 90 m to the east.
2. Right Turn Movement: The child goes 20 m.
3. Right Turn Movement: The child goes 30 m.
4. North Movement: The child goes 100 m to the north.
To calculate the total distance, we need to find the net distance covered in the east and west directions, and the net distance covered in the north and south directions.
- East-West Net Distance: The child went 90 m to the east and did not move in the west direction, so the net distance in the east-west direction is 90 m.
- North-South Net Distance: The child went 100 m to the north and did not move in the south direction, so the net distance in the north-south direction is 100 m.
Using Pythagoras' theorem, we can calculate the net distance between the starting point and where the child meets his father:
Net Distance = √((East-West Net Distance)^2 + (North-South Net Distance)^2)
= √((90)^2 + (100)^2)
= √(8100 + 10000)
= √(18100)
≈ 134.71 m
Therefore, the child meets his father approximately 134.71 m away from the starting point.
Since the closest option to this calculated distance is 100 m (option B), option B is the correct answer.
1. East: The child goes 90 m in the east to look for his father.
2. Right Turn: The child turns right and goes 20 m.
3. Right Turn: The child turns right again and goes 30 m to reach his uncle's house.
4. North: From the uncle's house, the child goes 100 m to the north and meets his father.
Now let's calculate the distance between the starting point and where the child meets his father:
1. East Movement: The child goes 90 m to the east.
2. Right Turn Movement: The child goes 20 m.
3. Right Turn Movement: The child goes 30 m.
4. North Movement: The child goes 100 m to the north.
To calculate the total distance, we need to find the net distance covered in the east and west directions, and the net distance covered in the north and south directions.
- East-West Net Distance: The child went 90 m to the east and did not move in the west direction, so the net distance in the east-west direction is 90 m.
- North-South Net Distance: The child went 100 m to the north and did not move in the south direction, so the net distance in the north-south direction is 100 m.
Using Pythagoras' theorem, we can calculate the net distance between the starting point and where the child meets his father:
Net Distance = √((East-West Net Distance)^2 + (North-South Net Distance)^2)
= √((90)^2 + (100)^2)
= √(8100 + 10000)
= √(18100)
≈ 134.71 m
Therefore, the child meets his father approximately 134.71 m away from the starting point.
Since the closest option to this calculated distance is 100 m (option B), option B is the correct answer.
