Fran works due north of home. Her husband Alan works due east. By the time Fran is 7 miles from home, the distance between them is one mile more than Alan's distance from home. How far from home is Alan? Miles

Please and thank you in Advanced!!!

Did you mean "walks" instead of "works" ?

Not that it matters much, I get a right-angled triangle with sides 7, x, and x+1

(x+1)^2 = x^2 + 7^2

x^2 + 2x + 1 = x^2 + 49

2x = 48

x = 24

check: 25^2 = 625

24^2+7^2 = 576+49 = 625
