1. The speed of longitudinal waves, called P waves, is 7700m/s . Transverse waves, called S waves, travel at a slower 4700m/s If the S wave arrives 2.2min after the P wave, how far away was the earthquake? You can assume that the waves travel in straight lines, although actual seismic waves follow more complex routes.
