Hans stands at the rim of the Grand Canyon & yodels down to the the bottom. He hears his yodel echo back from the canyon floor 5.20 seconds later. Assume that the speed of sound in air is 340 m/s. How deep is the canyon?

  2. d=vt
    340m/s(5.2s)=1768m

  5. Distance = Speed (or Velocity) * Time
    Distance = 340 * (5.2 / 2) = 884
