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
[tex]\begin{gathered} x=\frac{15\cdot48}{24} \\ \end{gathered}[/tex][tex]\begin{gathered} x=\frac{720}{24} \\ x=30 \end{gathered}[/tex]the height that was drill after 15 hours was 30 ft
