Each year, the river rises by 2 inches and tree grows by 1 inch,
so the relative gap between river level and house gets decreases by 1 inch every year.

So, the gap of 4 inches will be covered in 4 years, and then water will hit the house.

Jay was planning to go to another country to visit relatives. The trip to the airport was long and boring, and since he didn't have a license, his mother had to drive him.

Jay was driven to the airport once from his house when he realized that he forgot his passport at home. His mother went back, got it, then brought it back. He then said he left his wallet at home. She went to get it, came back, and he had some more bad news. He left his cell phone at home. She went to go get it, but exactly halfway back, she found it in the glove compartment. She brought it back to him immediately, and he went off with his flight.

Assuming that the average car speed was 75 kph, the distance between the house and airport was exactly 50 km, and ignoring facts such as U-Turn time, time talking to son at the airport, time getting items, etc, how long did it take for Jay to leave, with the time starting when he left his house?
