about how far does the s wave travel through earth in 13 minutes? 2,000 km 4,000 km 6,000 km 8,000 km

Answer:

B. 4,000 km

Explanation:

Step1: Locate 13 minutes on y - axis

Find 13 on the travel - time (minutes) axis.

Step2: Draw horizontal line

Draw a horizontal line from 13 on the y - axis until it intersects the S - wave line.

Step3: Draw vertical line

From the intersection point, draw a vertical line down to the distance (km) axis.

Step4: Read distance value

The vertical line intersects the distance axis at approximately 4,000 km.
