How long does it take him to complete the trip? (A) 4 hrs (B) 5 hrs (C) 7 hrs (D) 10 hrs (E) 12 hrs OA C Source: Magoosh As the others have shown, the fast approach is to recognize that: travel time = distance/speed = 350/50 = 7 hours However, we could also (if necessary) solve this by applying some common sense. Bob's speed is 50 miles per hour. In other words, for every 1 hour that elapses, Bob travels 50 miles So, after 1 hour of traveling, Bob has traveled 50 miles After 2 hours of traveling, Bob has traveled 100 miles After 3 hours of traveling, Bob has traveled 150 miles After 4 hours of traveling, Bob has traveled 200 miles After 5 hours of traveling, Bob has traveled 250 miles After 6 hours of traveling, Bob has traveled 300 miles After 7 hours of traveling, Bob has traveled 350 miles Answer: C 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 22 Aug 2016 Posted: 1770 messages Followed by: 28 members Upvotes: 470 BTGmoderatorDC wrote: Bob drives at an average rate of 50 mph from Berkeley to Los Angeles, a distance of 350 miles.
