Sound travels about _____ times faster in water than in air

Explanation:
Sound travels faster in a medium when the medium is stiffer (more resistant to compression) and only moderately affected by density. Water is much stiffer than air, so mechanical disturbances propagate through it more quickly, even though water is denser. The speeds are about 343 m/s in air and about 1,480 m/s in water, giving a ratio of roughly 4.3. So the best answer is about four times faster.
