Question

A vehicle covers a distance of 43.02 km in 2.4 litres of petrol. How much distance will it cover in one litre of petrol?

Answer 1

Given that:

• A vehicle covers a distance of 43.02 km in 2.4 litres of petrol.

To Find:

• How much distance will it cover in one litre of petrol?

Let us assume:

• It will cover x km in one litre of petrol.

According to the question.

↣ x : 1 = 43.02 : 2.4

↣ x/1 = 43.02/2.4

↣ x = 17.925

Hence,

• It will cover 17.925 km in one litre of petrol.

$\large\underline{\mathcal{\blue{GIVEN}}}$

$\:$

• A vehicle covers a distance of 43.02 km in 2.4 litres of petrol.

$\:$

$\large\underline{\mathcal{\pink{TO\:\:FIND}}}$

$\:$

• How much distance will it cover in one litre of petrol ?

$\:$

$\large\underline{\mathcal{\green{SOLUTION}}}$

$\\ \dashrightarrow \: \footnotesize\sf Distance\:covered\:in\:one\:litre\:of\:petrol = \dfrac{Distance\:covered\:in\:2.4\:litre\:of\:petrol}{Petrol\:used}$

$\\ \dashrightarrow \:\footnotesize \sf Distance\:covered\:in\:one\:litre\:of\:petrol = \dfrac{43.02}{2.4}$

$\\ \dashrightarrow \: \footnotesize\sf Distance\:covered\:in\:one\:litre\:of\:petrol = {\cancel{\dfrac{43.02}{2.4}}}$

$\:$

After cancelling 43.02 with 2.4, we get ::

$\\ \dashrightarrow \: \footnotesize\sf \purple{Distance\:covered\:in\:one\:litre\:of\:petrol = 17.925}$

$\:$

$\small\therefore\:{\underline{\sf{Distance\:covered\:in\:one\:litre\:of\:petrol = {\textsf{\textbf{17.925\:km.}}}}}}$

$\:$

• Distance of any object does not depend on direction of it's motion. It can be defined as path travelled by an object.

• For example :: If a bike travels south for 20 km and turns to travel north for 5 km, total distance travelled by bike will be 25 km.

• The distance can't be negative or zero and it is always more than the displacement of the object.

• Distance is a scalar quantity.

• Formula that we can use to calculate distance :: Distance = Speed × Time.
