Given :

Time,t = 4 s.

Speed of sound means the Velocity=330m/s.

So, as per the formula of Velocity,

We know that,

Velocity = Distance/Time

Distance = Velocity x Time.

So,lets put the values.

Distance = 330 x 4

Distance = 1320m.

Therefore the lighting is 1320m fare from the man.

I hope this will helps you.

Thanks.

Answer 2

t=4s

v=330m/s

d=v*t

d=330*4

d=1320m

d=1.32km
