Question 390997: If an earthquake travels 6 km/sec, how long will it take to reach 360 km?

Hello,
Since we know the earthquake travels 6 km in 1 sec, we can divide 6 into 360 to get:
60 seconds
We can set this up as a proportion:
6/1=360/x
Rewritten as:
6x=360 (by cross multiplying)
Now divide both sides by 6
and we get 60 seconds or 1 minute.
Make sense?
