The volcanic islands visible here formed as a result of a mantle plume.Researchers working on these volcanic islands have collected basalt samples for potassium-argon dating to determine when these islands formed Volcanic Island A has been dated to 7.6 million years ago.Volcanic Island C dates back to 3.4 million years ago and is 200 km away from A.Using the equation Rate = Distance/Time, calculate the rate of plate motion for this region.
