Question

В баке автомобиля 30 л бензна. Расход топлива на каждые 100 км пути состовляет 8 л. Хватит ли топлива автомобилю, если его скорость равна 80 км/ч, а время в пути составляет 5 ч?

Answer 1

1)80*5=400(км)-проедет автомбиль
Если на 100 км-8 л, то на 400 будет 32 л
То-есть:
2)8*4=32(л)-израсходует
4=400 км, тогда 1=100км
Получается топлива не хватит. Не хватит 2 литров.

Answer 2

Calculation of Fuel Consumption

To determine if the car has enough fuel for the given trip, we need to calculate the total fuel consumption based on the distance traveled and the fuel consumption rate.

Given information: - Fuel in the car's tank: 30 liters - Fuel consumption rate: 8 liters per 100 kilometers - Speed of the car: 80 kilometers per hour - Time of the trip: 5 hours

To calculate the total fuel consumption, we need to find the distance traveled. We can use the formula: distance = speed x time.

Using this formula, the distance traveled would be: distance = 80 km/h x 5 hours = 400 kilometers.

Now, we can calculate the total fuel consumption using the fuel consumption rate: fuel consumption = (distance / 100) x fuel consumption rate.

Substituting the values, we get: fuel consumption = (400 km / 100) x 8 liters/100 km = 32 liters.

Conclusion

Based on the calculations, the car would consume 32 liters of fuel for the given trip. Since the car has only 30 liters of fuel in the tank, it would not have enough fuel to complete the entire trip. Additional fuel would be required to complete the journey.

Please note that these calculations are based on the provided information and assume a constant fuel consumption rate. Actual fuel consumption may vary depending on various factors such as driving conditions, terrain, and vehicle efficiency.
