She can walk to work tagged by: M7MBA ##### This topic has 2 expert replies and 1 member reply ## Darcy lives 1.5 miles from work. She can walk to work Darcy lives 1.5 miles from work. She can walk to work at a constant rate of 3 miles per hour, or she can ride the train to work at a constant rate of 20 miles per hour. If she rides the train, there is an additional x minutes spent walking to the nearest train station, waiting for the train, and walking from the final train station to her work. If it takes Darcy a total of 15 more minutes to commute to work by walking than it takes her to commute to work by riding the train, what is the value of x? A. 10.5 B. 15 C. 25.5 D. 30 E. 60 The OA is A. Experts, what are the equations I should set to solve this PS question? I am a little confused.

A. 10.5 B. 15 C. 25.5 D. 30 E. 60 We are given that the distance to work is 1.5 miles. Thus, the time it takes Darcy to walk to work is 1.5/3 = 15/30 = 1/2 hour, or 30 minutes. When she takes the train, her time is x + 1.5/20 = x + 15/200 = x + 3/40 hours. Letâ€™s convert 3/40 hours to minutes: 3/40 hours = 3/40 x 60 = 4.5 minutes Since she spends 15 more minutes walking than she does taking the train: 4.5 + x + 15 = 30 x = 10.5 minutes Answer: A _________________ Jeffrey Miller Head of GMAT Instruction jeff@targettestprep.com See why Target Test Prep is rated 5 out of 5 stars on BEAT the GMAT.

Thanks in advanced. distance= 1.5 miles time taken to travel @ 3 miles per hour 3/1.5= 1/2 hours or 30 minutes she spends 15 more minutes in walking than commutuing by train+walk hence total time taken commutuing by train+walk = 30-15= 15 minutes some time is taken by travelling in train. so time x should be less than 15 Hence option A is correct ### GMAT/MBA Expert Legendary Member Joined 14 Jan 2015 Posted: 2667 messages Followed by: 122 members Upvotes: 1153 GMAT Score: 770 M7MBA wrote: Darcy lives 1.5 miles from work.

If she walks to work at 3mph, and she lives 1.5 miles away, it will take her 3t = 1.5 --> t = .5 hours, or 30 minutes to walk. We know it takes her 15 more minutes to walk than to take the train, so it must take her 30 -15 = 15 minutes to take the train. If she weren't waiting for an additional x minutes when taking the train, her trip would take 20t = 1.5 --> t = 1.5/20 = 4.5/60 hours = 4.5 minutes. So it she would have taken 4.5 minutes without having to wait, but it actually takes her 15 minutes, then she must have been waiting for 15 - 4.5 = 10.5 minutes.
