This is for tax accounting. I included the whole problem, but I only need help with the 4 red Xs in the second photo. Im not sure how to split the gain up. Could someone explain how?

Ken sold a rental property for $606,000. He received $142,000 in the current year and $116,000 each year for the next four years. $470,000 of the sales price was allocated to the building and the remaining $136,000 was allocated to the land. Ken purchased the property several years ago for $427,500. When he initially purchased the property, he allocated $342,500 of the purchase price to the building and $85,000 to the land.
