Answer:

C. 6,000 km

Step-by-step explanation:

v = speed at S-wave travel through the earth = 8 km/sec

t = time of travel for the S-wave through the earth = 13 minutes = 13 x 60 seconds = 780 seconds (Since 1 minute = 60 seconds)

d = distance traveled by S-wave in the given time interval

Distance traveled by S-wave in the given time interval is given as

d = v t

inserting the above values in the formula

d = (8 km/sec) (780 sec)

d = 6240 km

the closest choice is 6000 km at option C

So Option C

How to solve Which ordered pair is a solution for x − 3y = 1?

babunello [35]

There is no one answer (ordered pair) to this equation and the answer is found by graphing or trying out different values for each variable. Anyway, here are some solutions; (1,0), (4,1), (0,-1/3).
