user3149: The passed pawns are g and d pawns. Can the losing side draw such a rook endgame? Can you give some examples to how or why it can't be drawn? 

user8860: By definition if there's a "winning side" and a "losing side" then
the question is already answered :-)
But seriously, if you just want K+R+P(d)+P(g) vs. K+R, that's within
database range, so you can explore for yourself
here.
In general such positions are easy wins (note that the defending
King can "always" be cut off from one pawn or the other by a
Rook move to e or f), though naturally there are some initial positions 
where one pawn is lost tactically to leave a draw, and there can even
be "accidents" such as this:
6r1/8/7k/8/3P1KP1/8/8/4R3 w - - 0 0

1. Kf5?? Rf8+ 0-1
