A) 25 km
B) 250 km
C) 2500 km
D) 5000 km
Correct Answer: C
Solution :
[c] If x be the distance of epicentre from the seismograph, then \[\frac{x}{{{v}_{s}}}-\frac{x}{{{v}_{p}}}=4\times 60\] or \[\frac{x}{4.5}-\frac{x}{8}=4\times 60\] on simplifying, we get \[\,x=2500\text{ }km\]You need to login to perform this action.
