Answer in detail. For 4 years of work, three identical tractors consumed 5 liters of fuel and 1 telepenny consumed 7 liters of fuel. How many liters of fuel did 1 telepenny consume for 5 years of work?

To solve this problem, we need to find the rate of fuel consumption for each telepenny and then multiply it by 5 years. We can use the following formula:

rate = fuel / time

For the three identical tractors, the rate is:

rate = 5 / 4 = 1.25 liters per year

For the one telepenny, the rate is:

rate = 7 / 4 = 1.75 liters per year

Therefore, the amount of fuel that one telepenny consumed for 5 years of work is:

fuel = rate * time

fuel = 1.75 * 5 = 8.75 liters

The answer is 8.75 liters.
