Two cars, Car 1 and Car 2, that are initially separated by a distance $d$, are moving towards each other with speeds $v_1$ and $v_2$, respectively.

What is the distance traveled by Car 1 when it passes Car 2?

$d$

$ \cfrac {d}{2} $

$ \cfrac {v_1d}{v_1+v_2} $

$ \cfrac {v_2d}{v_1+v_2} $

$ \cfrac {v_1d}{v_1-v_2} $
