Question

Sailors on a ship hear the echo of their foghorn from a cliff, 3 seconds after it is sounded. If the sound travels at 330 m/S, work out the distance of the ship from the cliff.

Answer 1

Let velocity be v

     Distance be d

     Time taken be t

t = 3s

d= ?

V=330m/s

d=Vt/2

d=330×3/2

d=990/2

d=495metres
