Question

During a thunderstorm, the thunder is
heard 5 s after the flash of lightning is
seen. Calculate the distance of the place
lightning. It is given that speed of sound
air is 340 m/s.​

Answer 1

Explanation:

speed = distance/time

distance = speed * time 340* 5

Answer 2

Answer:

1730 meters

Explanation:

Let someone is Nita:

Suppose Nita is stood in open ground and she heard the lightning sound after 2 seconds of seeing it.

Given that,

Velocity of sound in air = 346 m/s

Time required = 5 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

346 m/s = Distance / 5 seconds

Distance = Velocity * Time

Distance = 346 * 5

Distance = 1730 meters

Therefore, the distance of Lightning from Nita is 1730 meters.
