How do you determine the difference in time between the arrival of the primary (p) wave and the arrival of the secondary (s) wave during an earthquake? (in other words, how do you determine t? ) add the s and p waves subtract the s from the p wave subtract the p from the s wave multiply the s and the p waves?
