2) Let the speed of the truck be x km/h and the speed of the car be (x+10) km/h.

From 7:30 to 13:30 is 6 hours, and from 8:30 to 13:30 is 5 hours. So, the truck travels 6x km and the car travels 5(x+10) km.

Since they meet each other, the sum of their distances traveled is equal to the total distance between them:

6x + 5(x+10) = 10x

Solving for x, we get:

6x + 5x + 50 = 10x

11x + 50 = 10x

x = 50

Therefore, the speed of the truck is 50 km/h and the speed of the car is 60 km/h.
