Need Assistance with Problem

  1. Apr 20, 2006 #1
    Question:
    Assume that a sound pulse travels with a constant velocity of 1,000 meters/second and that point A is separated from point B by a distance of 1,000,000 meters. Compute the time that elapses between the moment the sound pulse is transmitted at point A, strikes the object at B is reflected back, and arrives back at point A.

    Velocity = Distance
    Time

    Time = Distance
    Velocity

    Distance = velocity*Time

    I have the formulas, but what I am really looking for is a book that has these types of questions. Can anyone suggest a good book to answer these types of question.

    Thank you.

    Welcome to PF!

    Why do you need a book? If there is anything you don't understand please just ask here and someone will be more than willing to help you. Or would you just like more questions like these to practise on?
