On sending an ultrasonic wave from a ship towards the bottom of a sea, the time interval between sending the wave and receiving it back is found to be 1.5 s. If the velocity of the wave in seawater is 1400 m/s, find the depth of sea.

(velocity / time) / 2 = depth of the sea

$1400\times1.5$ / 2 = 1050 meters
