The appalachian trail is about 2,175 miles long. if a hiker averages 12 miles each day, how long will it take her to hike the length of the trail?

182 i think

Step-by-step explanation:

2,175 divided by 12 equals

181.25 rounded to 182 because the question talks about an entire day not just a portion of a day, or it does idk

it's both, now can you answer my most recent question?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
