Answer:
D = 230.2 Km
Explanation:
let distance between seismograph and focus of quake is D
From time distance formula we can calculate the time taken by the S wave

From time distance formula we can calculate the time taken by the P wave

It is given in equation both waves are seperated from each other by 17.8 sec
so we have
sec
Putting both time value to get distance value

D = 230.2 Km
