Yes this is how it was given.

[FONT="Comic Sans MS"]440 metres?

so the distance would still be 220m since it's an echo? No working out to do?

220metres...

I understand that but I just don't know how to work it out.. would the distance be the same?

An echo is a repeated sound caused by the reflection of sound waves from a surface. I still don't get what to do :( Should I multiply 220 by the 0.5? :/

Thanks. The other question is: A ship is 220metres from a large cliff when it sounds its foghorn. If the echo time is 0.5s, how far is the ship from the cliff? I don't understand what to do.
