Question

if there was a 4 - minute gap between the p and s wave, how far away was the earthquake? earthquake p - wave and s - wave travel time travel time (min) epicenter distance (x10² km) 1,000 km 2,000 km

Explanation:

Step1: Locate time - gap on graph

Find the 4 - minute gap on the travel - time axis.

Step2: Determine distance

Read the corresponding epicenter distance on the x - axis. For a 4 - minute gap between P and S waves, the distance is 2 (×1000 km), which is 2,000 km.

Answer:

2,000 km
