Answer:
It takes roughly 140 seconds or roughly 2 minutes and 20 seconds for sound to travel 28 miles.
Step-by-step explanation:
So, sound travels 1 mile in roughly 5 seconds.
To find out how long it takes for sound to travel 28 miles, multiply 28 by 5 (I'm pretty sure you know math!) So it takes roughly 140 seconds or roughly 2 minutes and 20 seconds for sound to travel 28 miles. (Remember! This is according to math, not science!) I hope you are safe!
