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 10.0 s later. How far is the ship from the shore

Answer 1

The distance of the ship from the shore is 1020m

Step-by-step explanation:

Given:

Speed, s = 340 m/s

Time, t = 10s

Distance, x = ?

The sound is going to have to go to shore, then come back.

The total round-trip distance is

D = speed X time

D = (340 m/s) * (6.0 s)

D = 2,040 m

But as previously stated, the sound had to get there, then come back. So the actual ship-to-shore distance is only half that.

x = D/2

`x = (2040)/(2) \\\\x = 1020m`

Therefore, the distance of the ship from the shore is 1020m
