How Far Does Ultrasound Travel in 0.2 Seconds?

[Aaraska_]

A submarine sends out a pulse of ultrasound to check how close it is to the sea bed. The reflected waves are detected 0.2 seconds later. Work out the total distance traveled by these detected waves. The speed of ultrasound is 1500m/s .

Welcome to the PF.

We can only help you if you show your best efforts to work on the solution. What are the Relevant Equations (involving speed, distance and time)? Can you show how to work with the Relevant Equations to start to figure out this problem?
