A crank, attached to a rope and bucket inside a well, is completely unwound and the bucket is at the bottom of the well. The crank's handle is at its farthest point from the

ground, 1.5 m. The handle is 0.5 m away from the middle of the crank. One full turn

of the crank raises the bucket 0.4 m.

a) Write an equation that models the distance of the crank's handle to the ground in

terms of the bucket's distance from the bottom of the well.
