Thunder and lightning

There was a glimpse of the sky, and we heard thunder in 4.5 seconds. The light spreads at 300,000 kilometers per second, so we can assume the flash instantly without delay. However, the sound's speed is much lower in the air, one-third of a kilometer per second. How far away is the storm?

Correct answer:

s =  1.5 km

Step-by-step explanation:

v=1/3=310.3333 km/s t=4.5 s s=v t=0.3333 4.5=1.5 km
