To estimate the distance from a lightning strike based on the time between seeing the flash and hearing the thunder, you can use the formula:
\[ \text{Distance (miles)} = \frac{\text{Time (seconds)}}{5} \]
If you are 2 miles from the lightning strike, you can set up the equation:
\[ 2 = \frac{\text{Time}}{5} \]
Now, to solve for time, multiply both sides of the equation by 5:
\[ \text{Time} = 2 \times 5 \] \[ \text{Time} = 10 \text{ seconds} \]
Thus, if you are 2 miles away from the lightning strike, the time between the flash of lightning and the sound of thunder would be 10 seconds.
