Question

$\text{A jeep spends}\frac{1}{7}\text{L of fuel to travel 1 km. The}\text{amount of fuel it uses to cover 4 km is}$

• A. $\frac{4}{7}L$
• B. $\frac{8}{7}L$
• C. $\frac{2}{7}L$
• D. $\frac{16}{7}L$

Answer 1

The correct option is A $\frac{4}{7}L$

$\text{Amount of fuel spent to cover 1 km}=\frac{1}{7}L$

$\text{Amount of fuel spent to cover 4 km}=(\frac{1}{7}+\frac{1}{7}+\frac{1}{7}+\frac{1}{7})L=\frac{(1+1+1+1)}{7}L=\frac{4}{7}L$
