Given :
A water well rig has dug to a height , H = 60 feet after one full day of continuous use .
To Find :
If the height is currently 143.6 feet how time it been running .
Solution :
It is given that height after 24 hours of use is 60 feet .
So , height loose in 1 hours is :
![h=\dfrac{60}{24}\ feet\\\\h=2.5 \ feet](https://tex.z-dn.net/?f=h%3D%5Cdfrac%7B60%7D%7B24%7D%5C%20feet%5C%5C%5C%5Ch%3D2.5%20%5C%20feet)
Now , time taken to cover a height of 143.6 feet is :
![t = \dfrac{143.6}{2.5}\ hours\\\\t=57.44\ hours](https://tex.z-dn.net/?f=t%20%3D%20%5Cdfrac%7B143.6%7D%7B2.5%7D%5C%20hours%5C%5C%5C%5Ct%3D57.44%5C%20hours)
Therefore , time taken is 57.44 hours .
Hence , this is the required solution .
