Homework Help: Astronomy

Posted by Andy on Thursday, November 24, 2011 at 8:36pm.

From Hawaii to the bend in the Hawaiian-Emperor chain is about 4000 km. If the Pacific plate is moving 8.0 cm a year, estimate how long ago the direction of plate motion changed. (The San Andreas Fault in southern California became active at about the same time!)

Does anyone have an answer?
