Answer:
40
Step-by-step explanation:
To find how much gasoline is needed for 480 kilometers, we will need to find how much is needed per kilometers:
13 liters is used for 156 kilometers
156/13 = 12 so 1 liter gasoline is spent per 12 kilometers
So for 480 kilometers we would need 40 liter gasoline because
480/12 = 40
Divide 1500 by 3 and that equals 500
