Question

If an earthquake occurred in Miami, Florida, then how long would it take for a seismic station in Seattle, Washington, to pick up that earthquake? The distance is roughly 5000 kilometers.

Answer 1

0.017s

Explanation:

Given parameter

Distance = 5000km = 5 x 10⁶m

Unknown:

time taken = ?

Solution:

We use the normal speed equation to solve this problem as we take the speed of the wave to be 3 x 10⁸m/s.

   Speed = $\frac{Distance }{Time taken}$

   Inputting the parameters:

             Time taken = $\frac{distance }{velocity of the wave}$

  Time taken = $\frac{ 5 000000}{3 00000000}$ = 0.017s
