Answer 2

Problem Statement

В автогонках приняло участие 13 машин. Сначала сошли с дистанции 4 машины, а потом еще 2. Сколько машин пришло к финишу?

Solution 1: Using Subtraction

To find the number of cars that finished the race, we can subtract the number of cars that dropped out from the total number of cars that participated.

The total number of cars that participated is 13. The number of cars that dropped out initially is 4. The number of cars that dropped out later is 2.

To find the number of cars that finished the race, we can subtract the number of cars that dropped out from the total number of cars that participated:

Number of cars that finished the race = Total number of cars - Number of cars that dropped out

Number of cars that finished the race = 13 - 4 - 2

Number of cars that finished the race = 7

Therefore, 7 cars finished the race.

Solution 2: Using Addition and Subtraction

Another way to solve this problem is by adding the number of cars that dropped out to the number of cars that finished the race.

The total number of cars that participated is 13. The number of cars that dropped out initially is 4. The number of cars that dropped out later is 2.

To find the number of cars that finished the race, we can add the number of cars that dropped out to the number of cars that finished the race:

Number of cars that finished the race = Number of cars that dropped out initially + Number of cars that dropped out later

Number of cars that finished the race = 4 + 2

Number of cars that finished the race = 6

Therefore, 6 cars finished the race.

Conclusion

In the given race, either 6 or 7 cars finished the race, depending on the method used to calculate the result.
