A car can travel 78 km using 6 litres of petrol. By using ratio and proportion methrfind how much petrol will be needed for trav
Anna71 [15]

Answer:

25 liters of petrol

Step-by-step explanation:

78 km = 6 liters

So the ratio is 78:6

Let's find the distance per liter:

78/6 = 13

So you travel 13 km per liter

To find the amount of liters for 325 km, you divide 325 by 13:

325/13 = 25

You would need 25 liters of petrol to travel 325 km.
