Before 10:15, only car is on the road, by which time it has travelled 80*(15/60)=20 km towards B.
So remaining distance as of 10:15 is 150-20=130 km.
When lorry starts, they approach each other at a total speed of (80+40)=120 km/h.
Elapsed time (since 10:15) when they meet is therefore
= 130/(80+40)=1h05m
You can work out the meeting time from here.
