Question

A water well drilling rig can dig -48 feet after one full day (24 hours) of continuous use. Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?

Answer 1

we have the next information

48 ft in 24 hours

x ft in 15 hours

x is the height of the drill after 15 hours

x can be calculated if we multiply 15 by 48 and then we divide the result between 24

$\begin{gathered} x=\frac{15\cdot48}{24} \\ \end{gathered}$$\begin{gathered} x=\frac{720}{24} \\ x=30 \end{gathered}$

the height that was drill after 15 hours was 30 ft
