Question: If a tank uses 1 liter of fuel to travel 5 km, how much fuel will it need to travel 100 km? (2023)

Options:

Correct Answer: 20 liters

Exam Year: 2023

Solution:

Fuel needed = Distance / Distance per liter = 100 km / 5 km/liter = 20 liters

If a tank uses 1 liter of fuel to travel 5 km, how much fuel will it need to travel 100 km? (2023)

If a tank uses 1 liter of fuel to travel 5 km, how much fuel will it need to travel 100 km? (2023)

Step 1: Understand that the tank uses 1 liter of fuel to travel 5 kilometers.
Step 2: Determine how many kilometers the tank needs to travel, which is 100 kilometers.
Step 3: Find out how many liters of fuel are needed for each kilometer by dividing 1 liter by 5 kilometers. This gives you 0.2 liters per kilometer.
Step 4: Multiply the total distance (100 kilometers) by the amount of fuel needed per kilometer (0.2 liters).
Step 5: Calculate 100 kilometers * 0.2 liters/kilometer = 20 liters.
Step 6: Conclude that the tank will need 20 liters of fuel to travel 100 kilometers.
