Kinematics question

A cage is descending into a well at a constant speed of 2 m/s when a stone falls through the wire in the cage. If the stone reaches the water at the bottom of the well 10 seconds before the cage, find the height above the water at which the stone fell out of the cage.

Thanks.

find t, substitute back to find displacement

I got displacement = 24.47, but the book says it's 24.04. And also, which formula did you use to find displacement of cage? :S

x = vt for constant velocity
