Neeta heard the sound of lightning after 4 seconds of seeing it what does the distance of the lightning from her
(the velocity of sound in air is 340 m/s)

Answer 1

speed = 340m/s
time = 4s
distance=speed*time
so distance = 4*340 = 1360 m
or 1.36 km

2d=v*td=v*t/2d=340*4/2d=680mthe distance is 680m
