WebCalculate the depth of water if the speed of sound in water is 1,480 m/s. Answer. Distance = speed × time. Speed = 1,480 m/s. Time for ultrasound to travel to seabed and back again = 0.1 s. Time for ultrasound to travel to seabed = 0.1 s ÷ 2 = 0.05 s. Distance to seabed = 1,480 × 0.05 = 74 m. The depth of water is 74 m.
