Free Falling Spiderman. I need to find height

[airgunde]

Spiderman steps from the top of a tall building. He falls freely from rest to the ground a distance of h he falls a distance of h/4 in the last 1.0 s of his fall. What is the height h of the building?





The attempt at a solution is on the photo.
I am stuck and don't know where to go to get rid of the h. What can I do?

for these type of problems, its always good to specify all the requirements

you almost got it , but i think you couldn't see how to proceed because it got messy and confusing
