Question

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

Answer 1

1)100:5=20(л)
2)30-20=10(л)
3)10-8=2(л)
4)80*2=160(л)
5)160-20-10=130(л)
Ответ:130л

Answer 2

1) 80*5=400(км)- проедет автомобиль
2) 400:100=4(раза)- больше 8 литров
3) 8*4=32(л)- понадобится
4) 30 л < 32 л
Ответ: топлива не хватит

Answer 3

Calculation of Fuel Consumption

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

Given: - Fuel in the tank: 30 liters - Fuel consumption per 100 km: 8 liters

We can calculate the total fuel consumption using the formula:

Total Fuel Consumption = (Distance / 100) * Fuel Consumption per 100 km

Calculation of Distance Traveled

To calculate the distance traveled, we need to know the speed of the car and the time taken for the trip.

Given: - Speed of the car: 80 km/h - Time taken for the trip: 5 hours

We can calculate the distance traveled using the formula:

Distance = Speed * Time

Calculation Results

Let's calculate the total fuel consumption and the distance traveled:

Total Fuel Consumption = (Distance / 100) * Fuel Consumption per 100 km

Distance = Speed * Time

Substituting the given values:

Distance = 80 km/h * 5 hours = 400 km

Total Fuel Consumption = (400 km / 100) * 8 liters = 32 liters

Conclusion

Based on the calculations, the car would require 32 liters of fuel for the given trip. However, the fuel tank only has 30 liters of fuel. Therefore, the car does not have enough fuel to complete the trip.

Please note that these calculations are based on the given 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.
