Solve Free Falling Object: Find Height of Ball

[Casimi]

Homework Statement

A ball, dropped from rest, covers three-fifths of the distance to the ground in the last second of its fall. From what height was the ball dropped?

The Attempt at a Solution

I have spent the past thirty minutes attempting to figure this out. I initially used a kinematic equation which gave me a new expression for the height and I attempted to put that expression into another kinematic equation but I still cannot seem to arrive at the correct answer.

Any advice or help on this would be appreciated!

No need, I finally figured it out :)
