Answer to yesterday's riddle: We could solve for distance directly, and come up with the summation of an infinite series. But since we're given the bee's speed, all we need is to solve for the time that the bee is in flight, since Distance=Speed * Time. To find the speed, we look at the trains: They are 180 km apart, travelling toward each other at 270 km/h (150 + 120) relative to a stationary observer. This means it takes them 2/3 of an hour, or 40 minutes, to collide. At 300 km/h over 40 minutes, the bee travels exactly 200 km.
P.S.: The B-Line is the name of one of the bus routes in Vancouver!
Takes a bit of computation... But once you get over that, it's simple no? Our next riddle is a challenge from Grafted:
I am the beginning of eternity, the end of time and space, the beginning of every end, and the end of every place. What am I?
