Answer:
receives an echo 0·3 seconds later. If the speed of sound in water is 1500 m/s calculate its depth.
ship using SONAR to find its depth
speed = distance / time
... distance = speed × time
distance = 1500 × 0·3 = 450 m
BUT this is the total distance travelled by the sound - so the depth is half of this.
Depth = 450 / 2 = 225 m
Answer is like this but it is not correct it is hint.
