From the trivia question Two planes headed towards each other, and are currently 440 miles apart. If one is going 240 miles per hour and the other 360 miles per hour, how far apart will they be four minutes before they meet? (Extra credit if you can do this one without pen and paper.)

The combined speed is 600miles per hour , means 10miles per min,means 40miles for four min.
