We are using the Pythagorean rule and I'm a little confused...
Solve each problem using a grid.
Round your answer to the nearest hundredth.
Dover is located at (1,2) and Goodlow is located at (5,7). How far apart are the 2 cities?
My answer is 6.40... am I doing this right? If not please explain. Thanks.

Reiny,
dist^2 = (51)^2 + (72)^2
= 16+25
= 41
distance = √41 = appr 6.40
You are correct.
