In 7 seconds, sound will travel a distance of \( 343 \text{ meters/second} \times 7 \text{ seconds} = 2401 \text{ meters} \). So, in just a quick 7-second pause, sound can travel a whopping 2401 meters! Isn't it fascinating that this speed can change based on various factors? For example, sound travels faster in water and even more so in steel! So if you ever have a conversation underwater or in a metal structure, you might find that you're chatting at super-speed!
