Tectonic plates move very slowly. If a tectonic plate moves 3 centimeters (cm) per year, how long in years would it take for the plate to move 3 meters (m)?

water: cools down faster, heats up faster, idk the last one

land: cools down slower, heats up slower, idk the last one

edit: if anything i answer is incorrect, i'm sorry. double check my work with someone else before using it. you for understanding.
