Solution

The correct option is B 2:4

$Distance covered (miles)$ $2$ $4$ $8$

$Fuel used (in L)$ $\frac{1}{20}$ $\frac{1}{10}$ $\frac{1}{5}$

$Fuel used to cover 1 mile (in L)$ $\frac{1}{40}$ $\frac{1}{40}$ $\frac{1}{40}$

$Fuel used to cover 2 miles = \frac{1}{20} L$

$Fuel used to cover 4 miles = \frac{1}{10} L$

$Ratio of the fuel used to cover 2 miles to the fuel used to cover 4 miles = 1 : 2 = 2 : 4$
