You can put this solution on YOUR website!
r, unknown rate QtoP
t, travel time, both, t=12
k, rate difference, k=8
d, length in kilometers, PQ, d=324


_________________rate___________time____________distance
PtoQ_____________r+k_____________t_______________(r+k)*t
QtoP______________r______________t_______________r*t
Total_____________________________________________d
