If these points were anywhere in (let's assume) 2D then you'd be right.

But, by an extension of the triangle inequality and noting that 310 + 200 + 150 = 660, there's only one interpretation, namely that these towns are in a straight line with Capital City and Little Village at the ends of that line.

Which is just as well, because the problem would not have a unique solution otherwise.

]]>I agree with bobbym.

I've given a hint for your triangle question, but that also leads to an odd result.

LATER EDIT:

No it doesn't. I've realised there's an upper bound as well as a lower bound. I've edited that post too.

Where are these questions from?

]]>Then I think that 3 of the towns all lie on a straight line.

]]>It is possible to find the distance you want but you seem to have a degenerate quadrilateral.

Could you check your distances again?

heres the problem:

The distance from Capital City to Little Village is 660 miles. From Capital City to Mytown is 310 miles, from Mytown to Yourtown is 200 miles, and from Yourtown to Little Village is 150 miles. How far is it from Mytown to Little Village?

no answer just please explain how to do this. You guys rock!
