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.
