from coordinate: 34.5390 73.5880 to coordinate:
 * 1. Use Google Maps (or Google Earth—your pick) to calculate the distance from the quake’s epicenter to LIGO.**

Distance in Kilometeres - 10,940.04 Distance in Miles- 6,797.82

--
 * 2. Calculate the seismic wave speed.**
 * The X-graph**

Distance in from epicenter to Handford- 10,940.04 Kilometers Time Difference: Time that hit Handford - Recorded Time (//approx)// 4:10 - 3:50 = 20 min
 * //*Time difference of p-wave//**//*//

10,940.04 Km / 20 min = 109.4040 Km/ min OR 1.8234 Km / sec


 * The Z-graph**

Distance in from epicenter to Handford- 10,940.04 Kilometers Time Difference: Time that hit Handford - Recorded Time (//approx)// 4:02 - 3:50 = 12 min
 * //*Time difference of p-wave//**//*//

10,940.04 Km / 12 min = 182.34 Km/ min OR 3.039 Km / sec

The difference is the time of arrival to Handford due to the different wave speed. The Given:
 * 3. Comment on any difference you see between the LIGO plots, and between the wave speed estimates obtained using each plot.**
