At what temperatures `(i n ^(@)C)` will the speed of sound in air be 3 times its value at `O^(@)C`?

Explanation

To solve the problem of finding the temperature at which the speed of sound in air is three times its value at 0°C, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between speed of sound and temperature**:
The speed of sound in air is given by the formula:
\[
V = \sqrt{\frac{\gamma R T}{M}}
