A volcanic island on the Pacific Plate has moved 200 km away from a hot spot. The oldest volcanics on the island are 5 million years old. What is the average rate of plate movement in cm/yr? There is a similar volcanic island on the Filipino Plate that hosts a population of 1 million people. Based on the rate you calculated for the Pacific Plate, assuming the Filipino Plate moves at the same rate, how long until the islands will collide if they are currently 950 km away and moving towards each other?
Recall that 1 km = 100,000 cm and R = d/t. Be sure to show all of your work.
