Question

Расстояние от Зареченска до заправочной станции в 7 раз меньше,чем от заправочной станции до Ивантеевки. Хватит ли машине 10 л бензина, чтобы доехать до заправочной станции, если на каждые 100 км пути ей требуется 9 л бензина?

Answer 1

800*9:100=72 км)- расстояние от Заречной до заправочной станции
72:7= 10л 200гр- не хватит

 

Answer 2

Distance Calculation

To determine if a car with a fuel capacity of 10 liters can reach the gas station, we need to calculate the distances involved. The given information states that the distance from Zarechensk to the gas station is 7 times smaller than the distance from the gas station to Ivanteevka.

Calculating Distances

Let's assume the distance from Zarechensk to the gas station is x kilometers. Then the distance from the gas station to Ivanteevka is 7x kilometers.

Fuel Consumption

The car requires 9 liters of fuel for every 100 kilometers. Therefore, for x kilometers, the car will need (9/100)*x liters of fuel to reach the gas station.

Solving for x

Given that the car has a fuel capacity of 10 liters, we can solve for x to determine if the car can reach the gas station.

(9/100)*x = 10
x = (10*100)/9
x ≈ 111.11 kilometers

Conclusion

Based on the calculations, the car would need approximately 111.11 kilometers to reach the gas station. Therefore, if the distance from Zarechensk to the gas station is less than 111.11 kilometers, the car will have enough fuel to reach the gas station.
