A ship measures the depth of a marine waters by using a sound device. The sound is
fired at the bottom of the waters and 6 seconds later the reflective sound arrives back on the ship. If the speed of the sound in the water is 800 m / s, determine the depth of the water !

we know that
v(velocity)=800 m/s
t(time)=6 second
d=?
to determine the depth we will use the formula
D=v×t/2
d=800×6/2
=2400 m
or 2,4 km
so the depth of the water is 2400 m or 2,4 km
