Question

Nita heard the sound of lighting after 4 seconds of seeing it.what was the distance of lightning from her the velicity of sound in air is 340m/s

Answer 1

light travels faster than sound so she saw lightning first and then sound

Answer 2

Answer:

1360 m

Explanation:

Suppose Nita is stood in open ground and she heard the lightning sound after 4 seconds of seeing it.

Given that,

Velocity of sound in air = 340 m/s

Time required = 4 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

340 m/s = Distance / 4 seconds

Distance = Velocity * Time

Distance = 340 * 4

Distance = 1360 meters

Therefore, the distance of Lightning from Nita is 1360 meters.
