Allison always leaves her office at 5.00pm and reaches her hotel in an...

To solve this question lets determine the information given :-
5:00 Allison leaves office------------=---------6:00 Allison reaches hotel
Allison & Britt meet
5:something Brittany leaves hotel---=-------- 6:00 Brittany reaches office
Time taken to retrieve laptop - 5 mins
Statement 1: Allison covers 2/3rd when she meets Britt
Since Allison covers entire distance in 1hr, she covers 2/3 distance in 40 mins. Therefore she meets Brittany at 5:40
Since Allison has covered 2/3rd the distance, Brittany must have travelled 1/3rd the distance to meet at the same point. Since Brittany reaches office at 6, she must be covering the remaining 2/3rd distance in 20 mins, therefore she must have already travelled for 10 mins.
Thus, time Brittany will reach office on Wed = 5:40 + return back 1/3rd distance + time to retreive laptop + entire distance
= 5:40 + 10 +5+ 30
= 6:25 Sufficient
Statement 2: Brittany leaves hotel at 5:30, therefore on normal days she covers entire distance in 30 mins as she reaches office by 6:00pm. Allison on the other hand must have travelled for half hour and covered half the distance by the time Brittany begins her journey.
Therefore it follows ratio of speed of britt:allison = 2:1, ratio of time (inversely proportional) = 1:2,
Allison has to cover 1/2 distance to reach hotel at 6:00, thus Allison and Brittany will cover 1/2d remaining in the ratio 2:1
before they meet. Therefore Allison would cover 1/3*1/2d and Brittany would cover 2/3 * 1/2d
Basis the above information we can calculate the total distance Brittany has to travel on Wednesday
2(2/3 * 1/2d) + d + Additional 5 mins to retrieve her laptop
2/3d + d + add 5 mins
We know that on normal days Brittany takes 30 mins to cover distance d
Therefore time at which she will reach on Wednesday = 5:30 + 20 (2/3d) + 30 (d) + 5 (time taken to retrieve)
= 6:25 Sufficient
Answer : D
