Question

Автомобиль проехал 280 км ,затратив 21л бензина . хватит ли бака бензина , вмещающего 40 л ,чтобы проехать 500 км

Answer 1

Вычислим расход топлива:
21 л / 280 км = 0,075 л/км

При таком расходе топлива за 500 км он потратит:

500 км * 0,075 л/км = 37,5 л 

37,5 л < 40 л

Ответ: Хватит.

Answer 2

Хватит, на 1 км тратится 21 л/ 280 км=0,075 л500 км
умножаем на 0,075=37,5 л понадобится

Answer 3

Calculating Fuel Efficiency

To determine if a 40-liter fuel tank is sufficient to travel 500 kilometers, we can calculate the car's fuel efficiency based on the given information.

The car traveled 280 kilometers and used 21 liters of gasoline. We can use this information to calculate the car's fuel efficiency in kilometers per liter (km/l).

Using the given data: - Distance traveled: 280 km - Fuel used: 21 liters

We can calculate the fuel efficiency as follows: - Fuel efficiency = Distance traveled / Fuel used - Fuel efficiency = 280 km / 21 liters - Fuel efficiency ≈ 13.33 km/l

Determining Fuel Tank Sufficiency

Now, let's determine if a 40-liter fuel tank is sufficient to travel 500 kilometers based on the calculated fuel efficiency.

Using the fuel efficiency of approximately 13.33 km/l, we can calculate the amount of fuel needed to travel 500 kilometers: - Fuel needed = Distance to travel / Fuel efficiency - Fuel needed = 500 km / 13.33 km/l - Fuel needed ≈ 37.51 liters

Based on this calculation, a 40-liter fuel tank would be sufficient to travel 500 kilometers, as approximately 37.51 liters of fuel would be needed for the journey.

Conclusion: The 40-liter fuel tank should be sufficient to travel 500 kilometers with a car that has a fuel efficiency of approximately 13.33 km/l.
