Two hikers, Alan and Ben, are 21 miles apart and walking towards each other. They meet in 6 hours. Find the rate of each hiker if Ben walks 0.3 mph faster than Alan.

Solution

Solution

first hike r^{'} s speed : 1.9

second hike r^{'} s speed : 1.6

Solution steps

Translate the problem into an equation:

x \cdot 6 + (x - 0.3) \cdot 6 = 21

Solve for

x, x \cdot 6 + (x - 0.3) \cdot 6 = 21 : x = 1.9

Find speed

first hike r^{'} s speed : 1.9

second hike r^{'} s speed : 1.6
