7. Imagine a hiker camping in the mountains. Just
before going to sleep he yells "WAKE UP," and the
sound echoes off the nearest mountain, returning
8 h later. How far away is that mountain?

Answer:

Explanation:

d = vt = 340m/s * (4hrs * (60 min/hr)*(60sec/min)) = 4,896,000 meters

  • speed of sound: 340m/s
  • we are using 4hrs as the time since it takes 8 hours to complete the roundtrip and we only need the time that it takes to complete half of the roundtrip which is 4hrs.

Hope that helps!
