A person has to walk 100m to go from position X in the northeast direction to the position Y and then to the west of Y to reach finally at position Z. The position Z is situated at the north of X and at a distance of 60m form X. Find the distance between X and Y
Answers
Given:
- Total distance from X to Z→ 100m
- Shortest distance between XZ → 60 m
To Find:
- Distance between XY
Solution:
(SEE THE ATTACHMENT ABOVE FOR DIAGRAM)
Let XY = x m
Therefore, YZ = (100 – x) m
In ∆ XYZ, ∠Z = 90°
By Pythagoras theorem:
XY^2 = YZ^2 + XZ^2
⇒ x^2 = (100 – x)^2 + 60^2
⇒ x^2 = 10000 – 200x + x^2 + 3600
⇒ 200x = 10000 + 3600
⇒ 200x = 13600
⇒ x = 13600/200
⇒ x = 68

The writer describes the hill station of Coorg located in the western ghats in the state of Karnataka. It is located midway between Bengalore and Mangalore. The suitable time to visit Coorg is from September to March. The place is famous for coffee plantations and spices. There are abundant rainforests which cover 30 percent of the area.
