Approximately how long does an earhquake P-wave take to travel the first 6500 kilometers after the earthquake occurs?

a. 6.5 min
b. 8.0 min
c. 10.0 min
d. 18.5 min

2 answers

Typical P-wave speeds are 6 km per sec.
Time = 6500 km/6 km/s = 1083 s = 18 min
d. is the closest answer to that

You should have been provided with some information abut the P wave speed.
This is so hard! I am in 6th grade an really, my teacher never taught us this, and we are having to do COLLEGE work. I was looking on another sight and it ACTUALLY said that it was 6.5. Miss calculation? I think maybe.... for the guy who said 6.5.
