Question

автомобиль Калина на 100 километров пути расходует 7 литров бензина Сначала он проехал 500 километров по воде на 200 километров меньше Сколько литров бензина потребовалось на весь путь

Answer 1

56 литров потребовалось

Answer 2

Calculation of Fuel Consumption

To calculate the total amount of fuel consumed for the entire trip, we need to consider the fuel consumption rate of the car and the total distance traveled.

Given that the car consumes 7 liters of gasoline per 100 kilometers, we can calculate the fuel consumption for the first part of the trip, where the car traveled 500 kilometers on water.

The car traveled 200 kilometers less on water than on land, so the distance traveled on land can be calculated as follows:

Distance on land = Distance on water + 200 kilometers

Substituting the given values, we have:

Distance on land = 500 kilometers + 200 kilometers = 700 kilometers

To calculate the fuel consumption for the first part of the trip, we can use the fuel consumption rate of 7 liters per 100 kilometers:

Fuel consumption for the first part of the trip = (Distance on land / 100) * Fuel consumption rate

Substituting the values, we have:

Fuel consumption for the first part of the trip = (700 kilometers / 100) * 7 liters = 49 liters

Total Fuel Consumption

To calculate the total fuel consumption for the entire trip, we need to add the fuel consumption for the first part of the trip (49 liters) to the fuel consumption for the second part of the trip, where the car traveled 100 kilometers.

Given that the car consumes 7 liters of gasoline per 100 kilometers, we can calculate the fuel consumption for the second part of the trip:

Fuel consumption for the second part of the trip = (100 kilometers / 100) * Fuel consumption rate

Substituting the values, we have:

Fuel consumption for the second part of the trip = (100 kilometers / 100) * 7 liters = 7 liters

To calculate the total fuel consumption for the entire trip, we can add the fuel consumption for the first and second parts of the trip:

Total fuel consumption = Fuel consumption for the first part of the trip + Fuel consumption for the second part of the trip

Substituting the values, we have:

Total fuel consumption = 49 liters + 7 liters = 56 liters

Therefore, 56 liters of gasoline were required for the entire trip.
