The reason for that is that P-waves (primary waves) travel faster than S-waves (secondary waves).
If we call
the speed of the primary waves and 
the speed of the secondary waves, and we call 
the distance of the seismogram from the epicenter, we can write the time the two waves take to reach the seismogram as
So the lag time between the arrival of the P-waves and of the S-waves is
We see that this lag time is proportional to the distance S, therefore the larger the distance, the greater the lag time.

Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
