Given information:
- The postman was returning to the post office which was in front of him to the south.
- When the post office is 80m away from him, he turned to the right and walks 50m to deliver the last letter.
- He continues walks in the same direction for 20 meter and then took a left turn and walks 80 meter.
To find: How many meters was he away from the post office?
Solution:
Let's assume that the initial position of the postman and the post office is as shown below:
P -> Postman's initial position
O -> Post office's position
|
|
P--|--O
|
|
Step 1: When the post office is 80m away from him, he turned to the right and walks 50m to deliver the last letter.
This means that the postman moves to the east direction for 50m. Now, the position of the postman and the post office is as shown below:
| 50m
|
P--|--O
|
|
Step 2: He continues walks in the same direction for 20 meter and then took a left turn and walks 80 meter.
This means that the postman moves to the south direction for 20m and then to the east direction for 80m. Now, the position of the postman and the post office is as shown below:
| 50m
|
P--|--+--+
| |
| |
| 20m|
| |
| |
| |
O-----+
Step 3: To find the distance between the postman and the post office, we need to find the length of the line joining the postman's position and the post office's position.
We can use Pythagoras theorem to find the length of the line.
Length of the line = √(50^2 + 80^2)
= √(2500 + 6400)
= √8900
= 94.34m (approx)
Therefore, the postman was 94.34m away from the post office.
Answer: Option D. 70m (approx)
