Question 34968This question is from textbook 
: I hate word problems. I have a tough time trying to comprehend them and extract a formula. Anyway-here's the problem: Earthquakes generate two circular waves, p-waves and s-waves, that travel outwards The p-waves travel faster, but the s-waves do the most damage. Suppose the p-waves have a velocity of 3.6 miles per second and s-waves have a velocity of 1.8 miles per second. How long after the earthquake will p-waves and s-waves be 80 miles apart?This question is from textbook
