Juli2301 [7.4K]

Answer:

Distance of the trail from the start to the end is 6\frac{17}{24} miles

Step-by-step explanation:

Distance from the start of a trail to the bird lookout point=3\frac{7}{8} miles

Distance from the bird lookout point to the end of the trail =2\frac{5}{6} miles

We want to find the difference of the trail from the start to the end, that is, how far is the starting point from the end point.

The distance between the start and end points

=3\frac{7}{8}+2\frac{5}{6}\\=\frac{31}{8} +\frac{17}{6}

=\frac{161}{24} =6\frac{17}{24} miles
