GATE 2024 CE (CE1) – Question 65
A bird is resting on a point P at a height of 8 m above the Mean Sea Level (MSL). Upon hearing a loud noise, the bird flies parallel to the ground surface and reaches a point Q which is located at a height of 3 m above MSL. The ground surface has a falling gradient of 1 in 2. Ignoring the effects of curvature and refraction, the horizontal distance (in meters) between points P and Q is _______________ (in integer).

Show answer and explanation
Correct answer: 10
Explanation
The bird flies parallel to the ground, so its path has the same falling gradient of 1 in 2. It descends $8 - 3 = 5$ m, so the horizontal distance is $5 \times 2 = 10$ m.
