Question

a) A car runs 16km using 1litre of petrol.how much distance will it cover using 2\3 4 litres of petrol?​

Answer 1

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• The distance covered in $\mathsf {2\frac{3}{4} }$ litre petrol = 44 km

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• A car runs 16 km using 1litre of petrol.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• The distance covered in $\mathsf {2\frac{3}{4} }$ litre petrol = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

• In 1 litre of petrol, car covers the distance = 16 km [Given]

$\sf\underline{\pink{\:\:\: So:-\:\:\:}}$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 16 \times 2\frac{3}{4} }$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 16 \times 2 + \frac{3}{4} }$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 16 \times \frac{8 + 3}{4} }$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 16 \times \frac{11}{4} }$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 4 \times 11}$

$\dashrightarrow \sf {Distance\: Covered\:in\:2\frac{3}{4} \: litre \: petrol = 44\:km}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

• The distance covered in $\mathsf {2\frac{3}{4} }$ litre petrol = 44 km

$\rule{200}{2}$
