Tectonic plates are large segments of the Earth$$s crust that move slowly. Suppose that one such plate has an average speed of $3\mathrm{.}4$ cm$/$yr$.$Part $($a$)$ Assuming the plate maintains the given speed for $1\mathrm{.}0$ s$,$ how far, in meters, does it move?Part $($b$)$ What is its average speed in kilometers per million years?
