Explanation:

Given parameters:

Distance of the seismic station from Blue mountain lake = 1200km

Unknown:

Time = ?

Solution:

To solve this problem, we must know that velocity is the displacement divide by time:

Velocity = $\frac{Displacement}{time taken}$

Since we are looking for time, lets make it the subject of the expression;

Time taken = $\frac{displacement }{velocity}$

velocity of the wave is a consant = 6km/s

Time taken = $\frac{1200}{6}$ = 200s
