Hello, the trick to this question is understanding that when the lorry and bus meet, the distance travelled by the bus plus distance travelled by the lorry equals the total distance between towns P and Q. I'm sure you can work out the average speed of the lorry yourself.
The answer I got is 72km/hr
I hope this helps.
