Question

if a car cover 82.5km in 5.5litres of petrol , how much distance will it cover in13.2litres of petrol

Answer 1

Answer:

$\red { Distance \: covered \: by \: 13.2 \: litres }$

$\green { = 198\:km }$

Step-by-step explanation:

We know if distance covered increases then the consumption of petrol increases.

Therefore, Distance covered directly varies with the number of litres of consumed .

$So, \frac{x_{1}}{y_{1}} = \frac{x_{2}}{y_{2}}$

$Here , \: x_{1} = 82.5 \:km , \: y_{1} = 5.5 \:litres$

$x_{2} = \red {?}\:km , \: y_{1} = 13.2 \:litres$

$By \: substituting \: \frac{82.5}{5.5} = \frac{x_{2}}{13.2}$

$\implies x_{2} = \frac{ 82.5 \times 13.2}{5.5}\\= 198\:km$

Therefore.,

$\red { Distance \: covered \: by \: 13.2 \: litres }$

$\green { = 198\:km }$
