Here is a DRT problem that is typical of the different cases the GMAT folks will ask. Don't get thrown off by the imagery and plausibility. :)

****************
Billy and Alice are 120 miles apart and riding animals towards each other from opposite directions. If Billy is traveling by riding a Cheetah at 60 mph and Alice is traveling by riding a Gazelle at 40 mph, how many minutes after Alice leaves will they meet, if Alice leaves 2 hours after Billy starts his journey with his cheetah?

a) 0
b) 20
c) 48
d) 72
e) 90

Answers?!?!?

I would have to say 0. In 2 hrs, Billy would have gone the entire 120 miles. His cheetah also probably devoured poor Alice's gazelle. Is this correct?
