distance = rate x time.
d = 10,000 m
t = solve for this in seconds
r = rate. I found one source that listed the speed of sound in air as approx 340 m/s and another that listed speed of sound in water as approx 1500 m/s. (You can go to google and look these numbers up if you want a more accurate answer.)
Plug in distance and rate and solve for time in each case. Subtract to see how much longer.
How much longer will it take for sound in air to travel 10km than in water
