At time t hours from 7:00, the distances traveled by the vehicles was
Matatu: 60t
Car: 80(t-2)
Since the total distance between K and M is 324 km, when the vehicles meet, we have
60t+80(t-2) = 342
t = 251/70 = 3:35:08

(A)
Matatu 7:00 + 324/60 = 12:24
Car: 9:00 + 324/80 = 13:03

I think B and C are now within your abilities...
