Question

. Sound is heard after 2 s, the lightning is seen in the sky during a cloudy day. Find
the distance of the location of lightning if speed of sound is 346 ms-1.

Answer 1

Speed of sound is 346 m/s i.e 346 m per second
Hence the origin of lightning is 2s away......
Thus the origin is -----
346m/s * 2s
=>346*2
=>692 m

Answer 2

Speed of sound is 346 m/s
Or, 346 metre per second
So the distance of lighting is,
Let the speed of lighting be X m/s
According to the question,
Lighting is 2 seconds fast than sound
So,
2 × 346 m/s = X m/s
692 m is the distance covered by the lighting
