Question

Два автомобиля проехали одинаковое расстояние израсходовали вместе 217 литров бензина. Первый автомобиль расходует 13 литров бензина на 100 километров второй 18 л. Какое расстояние проехал автомобили?

Answer 1

Х км проехали
13х/100+18х/100=217
13х+18х=21700
31х=21700
х=700км проехали

Answer 2

Problem Analysis

We are given two cars that have traveled the same distance and together have consumed 217 liters of gasoline. The first car consumes 13 liters of gasoline per 100 kilometers, while the second car consumes 18 liters. We need to find the distance traveled by the cars.

Solution

Let's assume the distance traveled by both cars is d kilometers.

The first car consumes 13 liters of gasoline per 100 kilometers, so it will consume (13/100) * d liters of gasoline.

The second car consumes 18 liters of gasoline per 100 kilometers, so it will consume (18/100) * d liters of gasoline.

Together, the two cars have consumed 217 liters of gasoline, so we can write the equation:

(13/100) * d + (18/100) * d = 217

Simplifying the equation:

(13d + 18d) / 100 = 217

31d / 100 = 217

Multiplying both sides by 100:

31d = 21700

Dividing both sides by 31:

d = 700

Therefore, the cars have traveled a distance of 700 kilometers.

Answer

The cars have traveled a distance of 700 kilometers.
