Martin left kingston driving at 80 km/h on highway 401. Linda followed 2 h later, driving in the same direction at 100 km/h. How far down the road will linda pass martin?

martin gets a two hour head start, so he has traveled 160 km when linda leaves

rate times time = distance , and they travel the same distance when linda passes

160 + 80t = 100t

solve for t, then determine the same distance each traveled
