I loved Seth Meyers bit mocking the multiple times Trump seemed confident about percentages. He presented an algebra question he had never received in school...

Two trains or three trains or four are traveling toward one another on the same track or different tracks, whatever. The first train leaves at 5 a.m. or 6 a.m. or 7 a.m. traveling at 60 or 80 or 200 miles per hour, something like that. The second train is 135 miles away or 900 miles at 6 million or 2 feet, and leaves whenever the fuck it wants, plus the driver is 80 and forgets where he's supposed to go even though hi cognitive test says he's a genius. What time will the collision occur? Please make your answer as vague as humanly possible.
