Question

Using that knowledge , how far did the two cars travel if Car 2 arrived (i)25 seconds after Car 1?..miles (ii) 45 seconds after Car 1?..miles The basis for locating earthquake epicenters based on the arrival times of different seismic waves. Time of faulting: You now have enough information to deduce exactly when the two cars started their trip. Knowing that Car 2 lags behind Car 1 by 1 second for every mile they travel, you can calculate how many miles they traveled from their starting point. (c) If Car 1 arrived at precisely 12:25:00. at what time did It start if it arrived 25 seconds before Car 2? 45 seconds before Car?? (Hint Determine how far the cars traveled. and use the velocity of Cal to estimate the time It needed to travel that distance.) Now put the two pieces of reasoning together. (d) if Carl arrives at precisely 1:45:22. followed at 1:46:37 by Cal 2. how fat did they travel? _ _ miles (e) At what time did they leave? (hour: minute: second)

Explanation / Answer

b) 25 miles

45 miles

c) 12:00:00

11:40:00

d) difference between the times of car1 and car2 = 75 sec

therefore the distance covered = 75 miles

e) 00:30:00
