Question

A ship sends ultrasonic waves that return from the sea bed and is detected after 2.80 seconds . If the speed o ultrasound through the sea water is 1531 meter per second ,what is the DISTANCE of the sea bed from the ship.

Answer 1

TIME= 2.80 S

SPEED = 1531 M/S

DISTANCE= ?

SPEED = DISTANCE / TIME

DISTANCE = SPEED X TIME

1531 X 2.80

=4286.8

SINCE IT IS DETECTED AND RETURNED,

4286.8 / 2

2143.4 M
