We're asked which of the two sources of water is closer to the zebra’s current position. 1) Moving at a constant rate, it takes the zebra 2 hours to reach the stream from its current position. Fact 1 tells us nothing about what this 'constant rate' is, so there's no way to determine the zebra's distance from the stream. We also know nothing about the zebra's distance from the pond. Fact 1 is INSUFFICIENT 2) Moving at a constant rate, it takes the zebra 2 hours to reach the pond from the stream. Fact 2 tells us nothing about what this 'constant rate' is, so there's no way to determine the zebra's distance from the pond. We also know nothing about the zebra's distance from the stream. Fact 2 is INSUFFICIENT Combined, we know... -Moving at a constant rate, it takes the zebra 2 hours to reach the stream from its current position. -Moving at a constant rate, it takes the zebra 2 hours to reach the pond from the stream. Unfortunately, we don't know if the two 'constant rates' that are mentioned are the same OR not, so there's no way to gauge the relative distances to the stream and pond. IF the two rates are equal, then the distances of the two water sources would be the same. IF one rate is faster than the other, then the distance of the water source would be farther away than the other source. Combined, INSUFFICIENT Final Answer: E GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com ### GMAT/MBA Expert GMAT Instructor Joined 08 Dec 2008 Posted: 12663 messages Followed by: 1246 members Upvotes: 5254 GMAT Score: 770 BTGmoderatorLU wrote: Source: Princeton Review A zebra must get water from either a stream or pond.

(2) Moving at a constant rate, it takes the zebra 2 hours to reach the pond from the stream. The OA is E Target question: Which of the two sources of water is closer to the zebra’s current position? Jump straight to.... Statements 1 and 2 COMBINED There are several scenarios that satisfy BOTH statements. Here are two: Case a: When traveling to the STREAM, the zebra heads EAST in a straight line at a constant speed of 1 mile per hour. So, the STREAM is 2 miles away from the zebra's starting point. When traveling from the STREAM TO THE POND, the zebra heads EAST at a constant speed of 1 mile per hour. So, the POND is 4 miles away from the zebra's starting point. In this case, the answer to the target question is the STREAM is closer to the zebra Case b: When traveling to the STREAM, the zebra heads EAST in a straight line at a constant speed of 1 mile per hour. So, the STREAM is 2 miles away from the zebra's starting point. When traveling from the STREAM TO THE POND, the zebra heads WEST at a constant speed of 1 mile per hour. So, the POND is 0 miles away from the zebra's starting point. In this case, the answer to the target question is the POND is closer to the zebra Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT Answer: E Cheers, Brent _________________ Brent Hanneson – Creator of GMATPrepNow.com Use our video course along with Sign up for our free Question of the Day emails And check out all of our free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMAT’s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert GMAT Instructor Joined 08 Dec 2008 Posted: 12663 messages Followed by: 1246 members Upvotes: 5254 GMAT Score: 770 Unfortunately, we don't know if the two 'constant rates' that are mentioned are the same OR not, so there's no way to gauge the relative distances to the stream and pond.

[/quote]Even if the zebra's speed is the same in both cases, we can't conclude anything about the distances, since we aren't told anything about the direction the zebra is traveling.
