Please explain and enlighten.  | Nope. Done it in my head. 3/8 one way, 5/8 the other. Difference is 2/8 (1/4). I've gotta cover 1/4 the distance in the same time as the train, thus 1/4 the speed = 15 mph. |
OOooohhhh. Now I see.
Good job Brad. I don't think I would have never gotten that one.

15 mph? That's a 4 minute mile. If this guy's like me then he's not going to "just make it to safety as the train passes" - HE'S GONNA DIE!!!
I don't think I could run 15 mph for more than a couch length nowadays.
Great math problem Jay! I like the brain benders.
