Question

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

Answer 1

Answer:

b, 4000

Step-by-step explanation:

Answer 2

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
