If you are 2 miles away from a lighting flash,
how long will it take the sound of thunder to 
reach you?

Under normal atmospheric conditions, the speed 
of sound is 770 miles/hour.

Time+=+%28Distance%29%2F%28Speed%29

Time+=+2%2F770 hours

To change hours to minutes we multiply by 60

Time+=+%282%2F770%29%2860%29 minutes

To change minutes to seconds we multiply by 60

Time+=+%282%2F770%29%2860%29%2860%29

Punch that into a calculator and get:

Time = 9.350649351 seconds 

or about 9.4 seconds.
