Question

A ship sends a pulse of ultrasound and receives an echo 0•3 seconds later. If the speed of sound in water is 1500 m/s calculate its depth.

Answer 1

speed = distance/time
speed = 1500m/s
time= 0.3 sec
then
1500×0.3=450m is total distance them divide it by 2 the ans is 225m

Answer 2

speed = distance/time

speed = 1500m/s

time= 0.3 sec

then

1500×0.3=450m is total distance them divide it by 2
