Answer 2

According to the search results, it seems that you are asking about the working hours of two tractors and the total working hours of all the tractors. Let's break down the information and calculate the answers.

Given Information:

- First tractor: 9 hours - Second tractor: 7 hours - Difference in working hours between the two tractors: 14 liters

Calculation:

To find out how many hours each tractor works in one hour, we can divide the difference in working hours (14 liters) by the difference in working hours between the two tractors (9 - 7 = 2 hours). This will give us the working hours per hour for each tractor.

- Working hours per hour for each tractor: 14 liters / 2 hours = 7 liters per hour

Now, let's calculate the working hours for each tractor and the total working hours for all the tractors.

- Working hours for the first tractor: 9 hours + 7 liters/hour = 16 hours - Working hours for the second tractor: 7 hours + 7 liters/hour = 14 hours

To find the total working hours for all the tractors, we need to know the number of tractors. If you provide the number of tractors, I can calculate the total working hours for you.
