Answer:

The distance covered by the lighting flash is 1700 meters.

Step-by-step explanation:

Given that,

The speed of sound travels in air at a speed of about 340 meter second, v = 340 m/s

The sound of thunder is heard 5 seconds after the flash of lightning is seen, t = 5 s

To find,

The distance far away was the lightning flash.

Solution,

The distance covered by the lighting flash is given by the product of speed and time. It is given by :


d=v* t


d=340\ m/s* 5\ s

d = 1700 meters

So, the distance covered by the lighting flash is 1700 meters. Therefore, this is the required solution.
