Question

· Nita heard the sound of lightning

after 4 seconds of seeing it. What
was the distance of the lightning
from her?
(The velocity of sound in air is 340
m/s?)
​

Answer 1

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 = 340 * 4

Distance = 1360 meters

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