Today’s Question - "Just watch the road will you!" Smiling Sal is driving on the road between Tedium and Oblivion. He is driving at a steady speed. He notes that every three minutes he meets a bus coming toward him and every six minutes a bus overtakes him. How often do the buses leave from the terminal in each town?

Reveal Answer Answer - The buses have an even schedule (as buses often do). Because he is moving toward the oncoming buses he sees more of them (naturally). So....in an hour he sees 20 oncoming (three minutes) and 10 overtaking (six minutes). So that's 30 in an hour. If he were stopped, he would see 15 from either direction. Therefore, the buses leave every four minutes (60 minutes \xc3\xb7 15). I wish I was on that route. \x0c Cashin\xe2\x80\x99s Comments November 17, 2015 Page 3 of 3
