Question

jan's old car travelled 198 km in 11 litres of diesel. He brought a new car that could travel twice as far on each litre diesel. how much fuel would jan need to travel 81 km in his new car?

Answer 1

Jan would have to put 4.5 liters of diesel In her new car.

Explanation:

to answer this question and show your work you will need to know how to do simple long division and dividing with decimals. If you dont know how to use the decimal, instead of writing a remainder, write a decimal and add a "0" next to your "81" and just continue your division. In the end, you should get 4.5

198 ÷ 11 =18

so 1 liter = 18 km

81 ÷ 18 = 4.5
