john is hiking glacier national park. he has now hiked a total of 17km and is 2km short of being 1/2 of the way done with his hike. write an equation to determine the total length in kilometers (h) of joshs hike 

Respuesta :

Let the hike distance be represented by = h

Given is :

17 + 2 = 19 km, this is 1/2 of the total length, so

[tex]19=(\frac{1}{2})h[/tex]

[tex]h=2\times19[/tex]

h = 38 km

Hence, the total length in kilometers is 38 km.
