Answer:
DC equals EC times AC all over BC
Explanation:
The parallel lines divide the segments proportionally, so you have ...
DC/AC = EC/BC
Multiplying by AC gives ...
DC = (EC·AC)/BC . . . . . . matches the 1st Choice
What I believe you are referring to is "the Blackstone" which was a largely sized meteorite.
P waves would arrive first because they are significantly more faster than the S waves.
