How long will it take for water to hit his house?

A man built his house above a river between two trees. He attaches his house to the middle of the two tree’s trunks. He does this because the river rises by 2 inches each years, but the trees grow 1 inch each year. If his house is 4 inches above the river how long will it take for water to hit his house?

    4 years. The trees grow one inch every year and the river rises 2 inches every year, hence every year the gap of 4 inches decreases by one inch. So after 4 years the level of the water will be exactly at the base of his house
