About how far does the S wave travel through Earth in 13 minutes?

A. 2,000 km

B. 4,000 km

C. 6,000 km

D. 8,000 km

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

b, 4000
