An airplane displays trip information to passengers in two way: how much time is left in the flight, and what percentage of the trip duration has been completed. When Curtis first checks the display, the clock reads 5:50, meaning that there are 5 hours and 50 minutes left for the trip, and the display shows that 12.5% of the trip has been completed. What will the clock show when the trip is 50% complete? A. 2:00 B. 2:25 C. 2:45 D. 3:10 E. 3:20 The OA is E. I'm confused by this PS question. Experts, any suggestion about how can I solve it? Thanks in advance. ### GMAT/MBA Expert Senior | Next Rank: 100 Posts Joined 16 Dec 2014 Posted: 94 messages Followed by: 4 members Upvotes: 2 GMAT Score: 770 Top Reply LUANDATO wrote: An airplane displays trip information to passengers in two way: how much time is left in the flight, and what percentage of the trip duration has been completed.

Thanks in advance. 5hr and 50 min to go = 87.5% of the trip 350 min = 7/8 of the trip --> multiply both sides by 4/7 to get to 50%! 200 min = 4/8 trip = 1/2 trip = 50% of the trip --> make sure you convert back the minutes to hr/min format! 3hr 20 min = 50% of the trip ### GMAT/MBA Expert Elite Legendary Member Joined 23 Jun 2013 Posted: 9942 messages Followed by: 492 members Upvotes: 2867 GMAT Score: 800 Hi LUANDATO, We're told that an airplane displays trip information to passengers in two way: how much time is left in the flight, and what percentage of the trip duration has been completed. When the clock reads 5:50, the display shows that 12.5% of the trip has been completed. We're asked for the time that the clock will show when the trip is 50% complete. We can use the Answer choices 'against' the prompt and TEST THE ANSWERS. To start, knowing basic fraction-to-decimal conversions will save you some time on Test Day. Here, 12.5% is 1/8; the trip is 1/8 complete when 5:50 is left on the clock. This implies that the ENTIRE trip is certainly more than 6 hours in length (since there's no way that 10 minutes is 1/8 of the trip) and HALF the time would be greater than 3 hours. Thus, the correct answer must be either D or E. Let's TEST Answer D) 3:10 IF HALF the trip would take 3:10, then.... the FULL trip would take 6:20 6:20 = 6 hours 20 minutes = 6(60) + 20 = 380 minutes 6:20 - 5:50 = 0:30 = 30 minutes (380 minutes)(1/8) = over 40 minutes These 2 values do NOT match one another, so this CANNOT be the answer. There's only one Answer left...
