Question

On a day when the speed of sound is 340 m/s, a ship sounds its whistle. The echo of the sound from the shore is heard at the ship 6.0 s later. How far is the ship from the shore?

(A) 56.7 m 

(B) 113 m 

(C) 1020 m 

(D) 2040 m 

(E) 4080 m

Answer 1

The correct option is: (C) 1020 m 

Explanation:

The time for the sound to travel the one way distance to the shore is half of the total time (6/2 =3 sec). Then use v= d /t to determine the distance.
