You can put this solution on YOUR website! Jane works due north of home.
her husband ben works due east.they leave for work at the same time.
by the time jane is 5 miles from home,the distance between them is one mile more than ben's distance.
how far is ben from home?
:
let x = Ben's distance from home
then
(x+1) = the distance between them when J is 5 miles from home
:
This is a pythag problems a^2 + b^2 = c^2, where
a = 5, b = x, c =(x+1)
:
5^2 + x^2 = (x+1)^2
25 + x^2 = x^2 + 2x + 1
subtract x^2 from both sides
25 = 2x + 1
25 - 1 = 2x
24 = 2x
x = 12 mi is Ben's distance from home

Check this out:
25 + 144 = 169 which is 13^2
