Answer:
![(1)/(2)\cdot h-2=17](https://img.qammunity.org/2021/formulas/mathematics/high-school/glh3v1onbifmfz81jq2y1asqf5ksr0nbn7.png)
Total length of Josh's hike is 38 km.
Explanation:
Please consider the complete question.
Josh is hiking Glacier National Park. He has now hiked a total of 17 km, and is 2 km short of being 1/2 of the way done with his hike
Write an equation to determine the total length in kilometers (h) of Josh's hike. Find the total length of Josh's hike. (km)
Let h represent the total length in kilometers.
1/2 of the total distance would be
.
Now we will subtract 2 to half of the distance as Josh is 2 km short of being 1/2 of the way.
![(1)/(2)\cdot h-2](https://img.qammunity.org/2021/formulas/mathematics/high-school/68l6l8u8tmqhjtnyhac36mo2egwerz3szq.png)
Now we will equate total distance covered by Josh with 17 km as:
![(1)/(2)\cdot h-2=17](https://img.qammunity.org/2021/formulas/mathematics/high-school/glh3v1onbifmfz81jq2y1asqf5ksr0nbn7.png)
Therefore, our required equation would be
.
Let us solve for h.
![(1)/(2)\cdot h-2+2=17+2](https://img.qammunity.org/2021/formulas/mathematics/high-school/6p1ocvmwuwbo5w6y29xrw7q4oiqzq39w44.png)
![(1)/(2)\cdot h=19](https://img.qammunity.org/2021/formulas/mathematics/high-school/f6t3r3ljc4z47idv2mfd03lmruutyrz6qh.png)
![(1)/(2)\cdot h\cdot 2=19\cdot 2](https://img.qammunity.org/2021/formulas/mathematics/high-school/t37jjq73iymrp49jno61tmlkyfdqsw54oo.png)
![h=38](https://img.qammunity.org/2021/formulas/mathematics/high-school/k35712puutg33smvta1zk2ixa0r21jqzj6.png)
Therefore, the total length of Josh's hike is 38 km.
