The Hawaiian Islands formed as a result of tectonic plate movement over a volcanic hot spot. The rate of plate movement can be calculated using the distance that an island is from the hot spot and the age of the island. A scientist determines that one of the islands is 4860 kilometers from the hot spot and is 6.5 * 107 years old. Which of the following statements are true? Select three that apply.

A. The rate of plate movement is approximately 7.5 cm per year.

B. The rate of plate movement is approximately 7.5 * 10-5 km per year.

C. In a million years, the plate has moved a distance of approximately 75 m. D. In a million years, the plate has moved a distance of approximately 7.5 * 107 mm.
