Question

Please, help me :)

A train leaves Chicago traveling west at 60 miles per hour. An hour later, at 12 noon, another train leaves Chicago and travels east at 80 miles per hour.

Answer 1

60+60 - hour heads up
80x-each hour travels 80miles
And both have a variable (x) that represent the number of hours
Equation:
60+60x=80x
Combine terms:
60=20x
Divide both sides by 20:
X=3
Soooo that means at 3:00pm two trains will be at the same distance from Chicago which is 240 miles
Hope this helps
