Question

A water well drilling rig has dug to a height of –60 meters after one full day of continuous use.a)	Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?

PsyDAG · Answer

If it is a drill, you are dealing with depth rather than height. Is one full day = 24 hours? 24/60 = 15/x Solve for x. If the day is not 24 hours, substitute that value for 24.
