Question

The distance from Chicago to Cleveland to Cincinnati and back to Chicago is 900 miles. The distance from Chicago to Cleveland is 50 miles more than the distance from Cincinnati to Chicago, and the distance from Cleveland to Cincinnati is 50 miles less than the distance from Cincinnati to Chicago. Find each distance and classify the triangle formed by the three cities.

Answer 1

Chicago to Cleveland- 350 miles

Cleveland to Cincinnati-250 miles

Cincinnati to Chicago-300 miles

Type of triangle formed? - Scalene

Explanation:

so I first give each of them a letter, so I chose a for Chicago to Cleveland, b for Cleveland to Cincinnati, and c for Cincinnati to Chicago. Then I write some equations.
a+b+c =900

b=c-50

a=50+c

i then plug the a and b equation into the first one to get

50+c+c-50+c=900

The fifties cancel out, so we are left with 3c =900 so c=300

From this we can figure out the rest by substituting in 300 for c in the an and b equations.
300-50=250

300+50=350
