An ultrasonic wave is sent from a ship towards the bottom of the sea. It reflects off the bottom of the sea floor and comes back to a sound wave sensor on the boat.

The time between the sending and receiving of the sound wave in the water is 1.6 s. If the sound wave that is used has a frequency of 555 Hz and a wavelength of 2.7 m, how deep is the sea in meters?

1198.8 meters!
