If the conveyor belt moves a bottle from a loading dock to an unloading dock, is the distance that the conveyor belt moves the bottle less than 90 meters? (1 meter = 100 centimeters) 1) It takes the conveyor belt less than 1.2 minutes to move the bottle from the loading dock to the unloading dock. 2) It takes the conveyor belt more than 1.1 minutes to move the bottle from the loading dock to the unloading dock.

Given rate: 120 centimeters per second. Since the statements are in terms of MINUTES, calculate the number of minutes required to move the bottle 90 meters: 90 meters * (100 centimeters)/(1 meter) * (1 second)/(120 centimeters) * (1 minute)/(60 seconds) = (90)/(12*6) = 15/12 = 5/4 = 1.25 minutes In the conversion above, all of the colored units CANCEL OUT, yielding a result in terms of minutes. Implication of the yielded result: For the bottle to be moved 90 meters, the time = 1.25 minutes. Thus, for the bottle to be moved LESS THAN 90 METERS, the time must be LESS THAN 1.25 MINUTES. Question stem, rephrased: Is t < 1.25? Statement 1: Since t < 1.2, the answer to the rephrased question stem is YES. SUFFICIENT. Statement 2: If t = 1.2, the answer to the rephrased question stem is YES. If t = 1.3, the answer to the rephrased question stem is NO. INSUFFICIENT. The correct answer is A. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

T = 1.2 * 60 =72 sec T<72 sec Therefore D < 120 * 72 = 8640 m Statement 1 is SUFFICIENT. Statement 2 It takes the conveyors belt more than 1.1 minutes to move from the bottle from the loading dock to the unloading dock. T = 1.1 * 60 = 66 secs T > 66 s Therefore, D > 120 * 66 = 7920 cm D can be any value greater than 7920 cm D can be = 8,000 cm D can be = 10,000 cm Information given is not enough to arrive at a definite answer Statement 1 alone is SUFFICIENT. $$Answer\ is\ option\ A$$ • 1 Hour Free BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Get 300+ Practice Questions 25 Video lessons and 6 Webinars for FREE Available with Beat the GMAT members only code • FREE GMAT Exam Know how you'd score today for$0
