Solution

first hike r^{'} s speed : 3.3

second hike r^{'} s speed : 1.1

Solution steps

Translate the problem into an equation:

x \cdot 10 + (x - 2.2) \cdot 10 = 44

Solve for

x, x \cdot 10 + (x - 2.2) \cdot 10 = 44 : x = \frac{33}{10}

Find speed

first hike r^{'} s speed : 3.3

second hike r^{'} s speed : 1.1
