Plane and shockwave

  1. Jan 30, 2008 #1
    1. The problem statement, all variables and given/known data

    A plane passes from 900 meters over my head. I hear the shockwave after 2.2 seconds. At what speed in Mach is the plane flying ? Speed of sound = 331. 4 m/s

    2. Relevant equations

    Machs = speed of plane / speed of sound

    3. The attempt at a solution

    I dont have any clue where to go with this, maybe find the angle of the cone ? it gave me an angle of like .14 degrees and an impossible answer of the plane speed.... dah

    Thanks in advance
