Multiple Choice
If an earthquake has a total horizontal displacement of S meters along its fault line, then the horizontal movement M of a point on the surface of Earth d kilometers from the fault line can be estimated using the formula where D is the depth (in kilometers) below the surface of the focal point of the earthquake. Approximate the depth D of the focal point of an earthquake with S = 5 m if a point on the surface of Earth 7 kilometers from the fault line moved 0.67 meters horizontally. Round the answer to the nearest hundredth.
A) km
B) km
C) km
D) km
E) km
