DISTANCE FROM R TO S =X
DISTANCE FROM S TO A =Y
X+Y=237.........TIME TAKEN = 5 HRS
TIME TO TRAVEL X = X/45
TIME TO TRAVEL Y= Y/49
TOTAL TIME
X/45 + Y/49=5
49X+45Y=5*45*49............II
49(237-Y)+45Y=49*225
4Y=49(237-225)=49*12
Y=49*3=147=DISTANCE FROMSYRACUSE TO ALBANY

let's assume it's x miles from Rochester to Syracuse
and y miles from Syracuse to Albany
the question wants to know y.

we're looking for y, so let's get rid of x first
multiply both sides of the first equation by 45

subtract the first equation from the second.
