Question

Brandon rides his bike 7 miles south and then 24 miles west. About how far is he from his starting point

Answer 1

So a^2+b^2=c^2 so if you think of it as a triangle let the unknown distance be c. So 7^2=49 and 24^2=576. 576+49=625 so c= the square root of 625 which is 25. Therefore 25 is your answer
