Question

anonymous · Answer

Let  the distance he covered be x
Therefore as speed= distance/Time
(x/3)-----> uphill speed
(x/2)-----> downhill speed

anonymous · Answer

His speed downhill was 1 mph faster than his speed uphill.
So,
$$\frac{ x }{ 3 }+1=\frac{ x }{ 2 }$$

anonymous · Answer

$$\frac{ x }{ 3 }-\frac{ x }{ 2 }=-1$$

In the back of the book it says "6 mi".
