hey everybody...
Okay I just started physics and I'm looking through my practice problems and I have no idea even how to do this..

According to a rule of thumb, every five seconds between a lightning flash and the following thunder gives the distance of the storm in miles. Assuming that the flash of light arrives in essentially no time at all, estimate the speed of sound from this rule.

Thanks
