The approximate distance is 1 kilometer or about 3/5ths of a mile away.

Using the average speed of sound in air (343 m/sec or about 1125 ft/sec), the distance would be 1029 meters (3376 ft.). *The English value used is 1000 feet per second, although 1100 feet per second is a better approximation. Note also, that the speed of sound varies with the density of air, which depends on temperature and altitude.

Sheet lightning and heat lightning are descriptive terms rather than scientific. Sheet lighting is cloud to cloud lightning that is viewed from such a distance that there is no sound. Heat lightning can be either cloud to cloud or cloud to ground at same distance with the added element of color tinting from atmospheric particles as with a sunset.
You can watch the skies for darkening clouds and lightning in the distance. The best way to know if a thunderstorm might be threatening is to watch the weather on television or the Internet.
Heat lightning is lightning from a distant thunderstorm. Because of the great distance, you never hear the thunder, and usually do not see the bolt, but rather a flash in distant clouds. It is usually seen at night.
If it is a thunderstorm, you check how long it takes to hear the thunder after you see a lightning strike. For every five seconds, the lightning strike is about one mile away. The lightning causes the thunder, and the sound travels at a speed of about one mile per five seconds.
Possibly, because they are taller than you. DO NOT stand under a tree in a thunderstorm, but stay a short distance from a tree and make yourself small - crouch down.
Light is virtually instantaneous over any distance you'd be aware of a thunderstorm going on. Sound, however, takes five seconds to travel through air for each mile. If the thunder and the lightning are simultaneous, the lightning strike is very close to you. If the thunder is five seconds after the lightning, the lightning was one mile away. If the thunder is ten seconds after the lightning, the lightning was 2 miles away, and so on.

It depends on what distance from you the storm develops. If it develops a long way off, you'll see tall mushrooming tops. At night distance lightning would be visible. If it develops closer you may see darkening clouds, flashes of lightning in the storm and near the ground. As the storm moves closer a shelf cloud indicating the cool air outflow would be visible along with lightning and a curtain of precipitation. If it develops overhead, it might sneak up on you with wind, rain, hail, lightning and darkening skies.
