Question

Бак автомобиля наполнен бензином до 5/6 своего объёма. После пробега в 125 км бак оказался пустым на 4/9 своего объёма. Полный бак вмещает 54 л. Каков расход бензина на 50 км пути?

Answer 1

1)54:6*5=45 литров в баке было изначально; 2)54:9*5=30 осталось в баке после пробега; 3)45-30=15 литров израсходовали на 125 км; 4)15:125*50=6л Ответ: 6 литров требуется бензина на 50 км

Answer 2

1 - 4/9 = 9/9 - 4/9 = 5/9 - бака осталось наполненным после пробега.
5/6 - 5/9 = 15/18 - 10/18 = 5/18 - бака истачено после пробега.
54 : 18 • 5 = 15 (л) - бензина ушло на 125 км.
15 : 125 • 50 = 6 (л) - расход на 50 км.
Ответ: 6 л.

Calculation of Fuel Consumption

To calculate the fuel consumption for a distance of 50 km, we need to determine the amount of fuel consumed for a distance of 125 km and then use that information to calculate the fuel consumption for 50 km.

Given information: - The fuel tank was filled to 5/6 of its capacity. - After traveling 125 km, the tank was empty and had 4/9 of its capacity remaining. - The full tank capacity is 54 liters.

To find the amount of fuel consumed for 125 km, we can subtract the remaining fuel in the tank from the initial fuel level:

Initial fuel level = 5/6 * 54 liters Remaining fuel level after 125 km = 4/9 * 54 liters

The fuel consumed for 125 km can be calculated as: Fuel consumed = Initial fuel level - Remaining fuel level

To find the fuel consumption for 50 km, we can use the proportion: Fuel consumption for 125 km / 125 km = Fuel consumption for 50 km / 50 km

Let's calculate the fuel consumption step by step:

1. Calculate the initial fuel level: Initial fuel level = 5/6 * 54 liters = 45 liters

2. Calculate the remaining fuel level after 125 km: Remaining fuel level after 125 km = 4/9 * 54 liters = 24 liters

3. Calculate the fuel consumed for 125 km: Fuel consumed = Initial fuel level - Remaining fuel level = 45 liters - 24 liters = 21 liters

4. Calculate the fuel consumption for 50 km: Fuel consumption for 125 km / 125 km = Fuel consumption for 50 km / 50 km

Let's solve the proportion: Fuel consumption for 50 km = (Fuel consumption for 125 km / 125 km) * 50 km

Now, let's calculate the fuel consumption for 50 km using the values we obtained:

Fuel consumption for 50 km = (21 liters / 125 km) * 50 km

The fuel consumption for 50 km is approximately 8.4 liters.

Please note that the above calculation assumes a linear fuel consumption rate, which may not always be accurate in real-world scenarios. Factors such as driving conditions, vehicle efficiency, and driving habits can affect the actual fuel consumption.
