Answers
Answer:
Explanation:
80 metres
Given:
Ankur initially walks 20 meters towards the south. He then turns left and walks 40 meters. He finally turns left and walks 20 more meters.
To Find:
The distance between the initial and final points.
Solution:
1. It is given that Ankur initially walks 20 meters towards the south.
2. Now, he turns left and walks a total of 40 meters. Ankur has walked 40 meters towards the east.
3. Ankur finally turns left and walks a total of 20 meters, Ankur has walked 20 meters in the south direction again.
4. The distance covered by Ankur in the south direction is the same in both cases. Hence the final distance between the initial point and the final point is the distance covered by Ankur in the west direction.
5. Distance between initial and final points = Distance covered by Ankur in the west direction.
=> Distance between the initial and final points = 40 meters,
Therefore, Ankur is totally at a distance of 40 meters from the initial point.
