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?

1. 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.
