Question

A car covers a distance of 558 km in 36 litre of patrol.How far can it move on 15 litres of patrol???
plz do this in ratio method??

Answer 1

Answer:

1 km

Explanation:

558 km=36litre

?km=15 litre

558/36=15.5litre of petrol will be covered in 1 km

hence,

1km=1000m

u can continue futher

Answer 2

Answer:

232.5 km

Explanation:

We can solve it mainly using 2 methods

Method 1 (Unitary method)

We know that,

The car covers a distance of 558 km using 36 litres of petrol

So, the distance the car travels with 1 litre of petrol

= 558/36 = 15.5 km/L

This is known as the Mileage of the car.

Thus, with 1 L it can move 15.5 km

then, with 15 L, it can move 15.5 × 15 = 232.5 km

Thus, the car travels 232.5 km using 15L of petrol......

Method 2 (Ratio/Proportionality method)

Let the Car move 'x' km using 15L of petrol

We know that,

The car travels 558 km using 36 L of petrol

Also, it then covers x km using 15 L of petrol

We know that,

They will be proportional or the mileage for both will be the same then,

558/36 = x/15

Cross multiplying we get,

558 × 15 = 36 × x

8370 = 36x

x = 8370/36

x = 232.5 km

OR

The car travels 558 km using 36 L of petrol

Also, it then covers x km using 15 L of petrol

then, they must be proportional,

Thus,

558 : 36 :: x : 15

We know that,

Product of extremes = Product of means

558 × 15 = 36 × x

8370 = 36x

x = 8370/36

x = 232.5 km

Thus, it travels 232.5 km using 15L of petrol

Hope it helped and you understood it........All the best
