Question

A car runs 18 km using 1 litre of diesel. How much distance will it cover using 3(4/9) litres of diesel

Answer 1

We know that,

If the Distance travelled increases then the consumption of diesel increases.

Therefore, Distance directly varies with the number of litres of diesel.

$Let \: x_{1} = 18 \:km , \: y_{1} = 1\:litre$

$and\: x_{2} = ?\:km , \: y_{2} = 3\frac{4}{9} = \frac{31}{9}\:litre$

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

$\implies \frac{18}{1} = \frac{x_{2}}{\frac{31}{9}}$

$\implies x_{2} = \frac{31}{9} \times 18$

$\implies x_{2} = 31 \times 2$

$\implies x_{2} = 62 \:km$

Therefore.,

$3\frac{4}{9} \:km \: litres \:diesel$

$covers \: 62 \: km$
