Unitary method A car can cover a distance of 522km on 36litres of disesel. How far can it travel with 14litres,

maria [59]

Answer:

It can cover 203 km with 14 litres.

Step-by-step explanation:

Given that,

A car can cover a distance of 522km on 36litres of diesel.

522 km = 36 litres

1 l = (522/36) km

We need to find how far can it travel with 14 litres.

We can use the unitary method to solve it.

$14\ L=\dfrac{522}{36}\times 14\\\\=203\ km$

So, it can cover 203 km with 14 litres.
