There is a storm, in which lightning stroke (light wave) and thunder (sound wave) happened at the same time in a cloud. You are at a distance d from the storm, and you see the lightning almost instantly (speed of light in air is 3.00 x 108 m/s). Right when you see the lighting, you start counting in your head. Around 5 seconds later, you hear thunder. Given that the speed of sound in air is 340 m/s, find an estimate of the distance d from the storm.
