Question

A pole 12 meters long is leaning against a vertical wall of a building. if the foot of the pole is being pulled away from the wall at the rate of 2 meter per minute, how fast is the top of the pole sliding down the wall at the instant when the foot of the pole is 5 meters from the wall?

Thank you! :)
