From http://en.wikipedia.org/wiki/Speed_of_sound
Sound travels at 1550.744 m/s at T=25°.C and salinity 35 parts per thousand at a depth of 1000 m.
On that basis, you only have to multiply the speed by the time to get the answer.
The same article gives an empirical equation that links all three variables to the speed of sound, in case the conditions change.
What is the distance traveled in 22 s as a given sound moves through seawater at 25 C?
