The time between a flash of lightning and the sound of its thunder can be used to estimate the distance from a lightning strike . The distance from the strike is the number of seconds between seeing the flash and hearing the thunder divided by 5 . Suppose you are 5 miles from a lightning strike . How many seconds are between the flash and thunder ?
Question
In this case it is t/5=m, and when when we plug 5miles in for m we get t/5=5, this can then be simplified to t=5•5, or t=25
