Question

На одном грузовике работали 60 ч,а на другом-54 ч.При одинаковом расходе бензина в час на первой машине израсходовали бензина на 72 л больше,чем на второй.Сколько литров бензина израсходовали на каждой машине?

Answer 1

60-54=6ч- на столько больше работали на перовм грузовике

 72/6=12л- расход топлива 

60*12= 720 л - израсходовали на одном грузовике

54*12= 648л- на втором

 

Answer 2

1) 60-54 = 6 (часов)- больше работал первый грузовик.

 2) 72/6 = 12 (л/час) - расходует бензина один грузовик.

3) 12*60 = 720 (л) - израсходовал бензина первый грузовик.

4) 12*54 = 648 (л) - израсходовал второй грузовик.

Ответ: 720 литров бензина израсходовал первый грузовик, 648 литров - второй. 

Answer 3

Problem Analysis

We have two trucks that have worked for different hours, and we need to find out how much gasoline each truck consumed. The first truck worked for 60 hours, while the second truck worked for 54 hours. The gasoline consumption rate per hour is the same for both trucks. However, the first truck consumed 72 liters more gasoline than the second truck.

Solution

Let's assume that the gasoline consumption rate per hour for both trucks is x liters.

To find the total gasoline consumption for each truck, we can multiply the gasoline consumption rate per hour by the number of hours worked by each truck.

For the first truck: Total gasoline consumption = x liters/hour * 60 hours

For the second truck: Total gasoline consumption = x liters/hour * 54 hours

Since the first truck consumed 72 liters more gasoline than the second truck, we can set up the following equation:

x liters/hour * 60 hours = x liters/hour * 54 hours + 72 liters

Now, let's solve this equation to find the value of x, which represents the gasoline consumption rate per hour.

Calculation

To solve the equation, we can simplify it as follows:

60x = 54x + 72

Subtracting 54x from both sides of the equation:

6x = 72

Dividing both sides of the equation by 6:

x = 12

Therefore, the gasoline consumption rate per hour for both trucks is 12 liters.

Now, we can calculate the total gasoline consumption for each truck:

For the first truck: Total gasoline consumption = 12 liters/hour * 60 hours = 720 liters

For the second truck: Total gasoline consumption = 12 liters/hour * 54 hours = 648 liters

Therefore, the first truck consumed 720 liters of gasoline, while the second truck consumed 648 liters of gasoline.

Answer

The first truck consumed 720 liters of gasoline, while the second truck consumed 648 liters of gasoline.
