Question

Meg lives in Indianapolis and wants to visit her mom in Lima. She has been meaning to go to a chiropractor in Dayton, so she is wondering whether it makes sense to stop there on the way. Dayton is 165 miles east of Indianapolis, Lima is due north of Dayton, Indianapolis is 173 miles away from Lima, and there are straight roads connecting all three cities.
How many more miles would Meg drive if she stopped in Dayton first than if she drove directly to Lima?

Answer 1

First she would drive 165 miles.
Now we minus the distance of both cities. 173-165=
8 more miles.
