Question 1151291

{{{drawing ( 600, 600, -10, 10, -10, 10,
circle(2,0,.12),locate(2,-0.4,Ben),circle(3,5,.12),locate(3,5.5,Vivian),circle(3,0,.12),locate(3,-0.3,Carly),line(2,0,3,5),line(3,0,3,5),line(2,0,3,5),locate(2.3,0.5,1mil),locate(3,3,2mil),
graph( 600, 600, -10, 10, -10, 10, 0)) }}}

then, the distance of Ben's house from Vivian's house will be 

{{{d=sqrt(1^2+2^2)}}}

{{{d=sqrt(5)}}}

{{{d=2.236067‬}}}‭ 

{{{d=2.2‬}}} mil
