E. None of these


SOLUTION:

1. (Walking to a viewpoint) + (Driving back) = (6 hours 45 minutes)

2. (Driving to a viewpoint) + (Driving back) = (6 hours 45 minutes - 2 hours) = (4 hours 45 minutes), therefore (one way driving) = (4 hours 45 minutes)/2 = (2 hours 22.5 minutes).

3. From 1. (Walking to to a viewpoint) = (6 hours 45 minutes) - (2 hours 22.5 minutes) = (4 hours 22.5 minutes).

4. (Walking to to a viewpoint) + (Walking back) = (4 hours 22.5 minutes) + (4 hours 22.5 minutes) = (8 hours 45 minutes).

Answer: A.

Hope it's clear.

let t=hours to walk 1/2 distance
27/4-8/4=19/4 hours to drive total distance
(19/4)/2=19/8 hours to drive 1/2 distance
t+19/8-2=19/4
t=35/8=4 h 22.5 min
2t=8 h 45 min

Let the distance be D , speed of car be C , and speed of walking be W .

The first equation is : (D/C)+(D/W)=6 hr 45 min.
Second equation - (D/C)+(D/C)= 4 hr 45 min
We need to find 2D/W. The answer is 8 hr 45 min. ie option A.

W + D = 6 : 45 ------- (I)

D + D = 4 : 45

D = 2 : 22.5 -------(II)

Using (I) and (II)

W = 6 : 45 - 2 : 22.5

W = 4 : 22.5

W + W = (4 : 22.5) * 2

8 : 45 (A)

We let the walk rate = w and the car rate = c. We let the distance = d. We also convert 6 hours 45 minutes to 6 3/4 hours.

We can create the equations:

d/c + d/w = 6 3/4

and

d/c + d/c = 4 3/4


If we simply the second equation, we have:

2d/c = 19/4

d/c = 19/8

Substituting d/c = 19/8 in d/c + d/w = 6 3/4, we have:

19/8 + d/w = 6 3/4

d/w = 6 3/4 - 19/8 = 54/8 - 19/8 = 35/8

Notice that d/w is the one-way walking time, so the round-trip walking time would be:

2d/w = 2 x 35/8 = 35/4 = 8 3/4 hours = 8 hours 45 minutes

Answer: A

Quick approach - if driving saves 2 hours, not driving but walking will use 2 hours more. Hence 6h 45 mins +2 hours is 8 hrs 45 mins
