Question

A ship sends out ultrasound that returns from the seabed and is detected after 3.42 s. If the speed of ultrasound through seawater is 1531 m/s . What is the distance of the seabed from the ship?

Answer 1

Given:-

Speed of sound = 1531 m/s

Speed of sound = 3.42 s

Distance of sea bed from ship = Speed of sound  × time taken / 2

= 1531  × 3.42 / 2

= 2618 m

the distance of the seabed from the ship is 2618 m.

Answer 2

Distance of sea bed from ship = Speed of sound * time taken / 2

= 1531 * 3.42 / 2 = 2618 m
