You can put this solution on YOUR website!
d, the distance between points X and Y
RT=D, basic uniform rates travel rule
Time will be used here in hours.


___________________speed______________time_______________distance
GOING______________480___________________t________________d
RETURN_____________440_________________t+35/60____________d

d is for both going and returning, so expressions for RT are equal.
highlight%28480t=440%28t%2B7%2F12%29%29
Solve for t.
From there, you have d=480%2At.
