If 16 L petrol is required to cover a distance of 256 km, then how much petrol is required
to cover a distance of 400 km?​

Answer 1

25 liters of petrol is required to cover 400 km

Step-by-step explanation:

We are given that 16L petrol is required to cover a distance of 256 km

Now we are supposed to find how much petrol is required to cover a distance of 400km

Amount of petrol required to cover 256 km = 16 liters

Amount of petrol required to cover 1 km =  

Amount of petrol required to cover 400 km =  

Hence 25 liters of petrol is required to cover 400 km

Answer 2

$\huge \bf \underline{ \underline{Solution}}$

Using Unitary Method:-

$\frac{256}{16l} = \frac{400}{x} \\ = 16lx = 400 \\ = x = 25l$

Final Answer:-
