My car needs to go for a service in 2 871 km. I drove 1 264 km during the month. How many kilometres before I have to take my car for the services?

Here is the solution to the problem:

Problem: My car has to go for a service in $2871 \text{ km}$. I drove $1264 \text{ km}$ during the month. How many kilometres before I have to take my car for the service?

Step 1: Subtract the distance driven from the total distance remaining until service.

$$2871 \text{ km} - 1264 \text{ km} = 1607 \text{ km}$$

You have $\boxed{\text{1607 km}}$ before you have to take your car for service.
