Given that sound travels 1 mile in $\frac{1}{12}$ of a minute, we need to find the speed of sound in miles per minute and then convert it to miles per hour.

Step-by-Step Solution

1. Find the speed in miles per minute:

   If sound travels 1 mile in $\frac{1}{12}$ of a minute, we can find the speed in miles per minute by taking the reciprocal of $\frac{1}{12}$: $\text{Speed in miles per minute} = \frac{1}{\frac{1}{12}} = 12 \text{ miles per minute}$

2. Convert the speed to miles per hour:

   There are 60 minutes in an hour, so to find the speed in miles per hour, we multiply the speed in miles per minute by 60: $\text{Speed in miles per hour} = 12 \text{ miles per minute} \times 60 \text{ minutes per hour} = 720 \text{ miles per hour}$

Simplified Answer

The approximate speed of sound is $720$ miles per hour.
