A man standing between two cliffs produces a sound and hears two successive echoes at intervals of 3 s and 4 s respectively. Calculate the distance between the two cliffs.
The speed of sound in the air is `330ms^(-1)`.

Explanation

To solve the problem of finding the distance between two cliffs based on the echoes heard by a man standing between them, we can follow these steps:

### Step 1: Understand the scenario
The man produces a sound that travels to each cliff and reflects back to him, creating echoes. The time intervals for the echoes are given as 3 seconds and 4 seconds.

### Step 2: Identify the speed of sound
The speed of sound in air is given as \( v = 330 \, \text{m/s} \).
