 The distance traveled was 6 miles  (6 mph times 1 hour).

The total distance traveled was 12 miles.

The downhill journey lasted   (6 mi) / (12 mph), or 1/2 hr.

Thus, the average speed was 

12 miles         12 mi
------------- = ------------ = 8 mph
(1 1/2 hr)       (3/2) hr

So the scale is 3/4 cm for every 6 meters

So if you have 8 cm, we want to find the dimension of the actual wall

convert cm to meters

0.75 cm = 0.0075 meters

8 cm = 0.08 meters

\frac{0.0075}{6} = \frac{0.08}{x}

Cross Multiply

0.0075x = 0.48

x = 64 meters
