If you see the flash and then count the number of seconds until the thunder.

Take the speed of sound at 340.29 m/s = 0.211 miles per second. A good estimate is for every 5 seconds of delay equals 1 mile away. I answered a question similar to this one, earlier today.

How do you calculate lightning distance?

You can estimate the distance of a lightning strike by counting the seconds between seeing the lightning and hearing the thunder. Divide this number by 5 to get the distance in miles or by 3 to get the distance in kilometers. Keep in mind this method gives an approximate distance.

You hear thunder 13.9 seconds after a lightning flash how far are you from lightning?

You are approximately 2.7 kilometers (1.7 miles) away from the lightning strike. Sound travels at about 343 meters per second, so by dividing the time gap of 13.9 seconds by the speed of sound, you can calculate the distance.


When Sound travels at 348 ms in the warm air surrounding a thunderstorm. How far away was the place of discharge if thunder is heard 4.40 s after a lightning flash?

To determine the distance of the lightning strike, we use the formula Distance = Speed x Time. Given the speed of sound is 348 m/s and the time taken for thunder to be heard is 4.4 seconds, we can calculate the distance. Distance = 348 m/s x 4.4 s = 1531.2 meters. Therefore, the lightning strike was approximately 1531.2 meters away.

How far does lightning travel in the ocean and what factors influence its distance?

Lightning can travel up to 10 miles in the ocean. Factors that influence its distance include the conductivity of the water, the strength of the lightning bolt, and the presence of any obstacles in the water.


If you know the input distance and output distance of a machine which quantity can you calculate?

You can calculate the mechanical advantage of the machine.


How long does it take to hear thunder after lightning strikes?

The time it takes to hear thunder after lightning strikes is typically about 5 seconds for every mile of distance between you and the lightning.


If you hear thunder 5 s after seeing a flash of lightning the distance to the lightning strike is about?

Roughly 1 mile away. Sound travels at about 1 mile every 5 seconds, so the time difference between seeing the lightning and hearing the thunder can give you an estimate of the distance to the lightning strike.


How do you calculate time from speed and distance?

time = distance ÷ speed
