Answer:

Explanation:

amount taken by the car to cover 150 km of distance= 20 liters

(which is given to us)

amount which the car takes to cover 1 km=20/150=0.133 liters

now we can calculate the amount that the vehicle will consume by travelling 45 km ,

the amount consumed by the car = 0.133*45

=5.985 litres

Answer:

6 litres

Explanation:

In order to solve this problem, you can set up a proportion based on the given information:

The car uses 20 litres to cover 150 km.

Let's represent this as a ratio:


\sf (20\: litres )/( 150\: km)

Now you want to find out how many liters the car will use to cover 45 km. Let's represent this as a proportion:


\sf (x \:litres )/( 45 \:km)

Set up the proportion:


\sf \sf (20\: litres )/( 150\: km) = \sf (x \:litres )/( 45 \:km)

Criss Cross-multiply:


\sf 20 * 45 = 150 * x


\sf 900 = 150x

Now, solve for x:


\sf x = (900 )/(150)


\sf x = 6

So, the same car would use 6 liters to cover a distance of 45 km.
