Question

If a car can cover 88$km$ using $5\frac{2}{4}$ litres of fuel, the kilometres covered by the car in $2\frac{1}{2}$ litres of fuel is .

• A. 40
• B. 220
• C. 44
• D. $40\frac{1}{2}$

Answer 1

The correct option is A 40

Given that $5\frac{2}{4}$ litres of fuel can help cover 88kms.
Thus, the distance that can be covered with $2\frac{1}{2}$ litres of fuel is $\frac{88\times 2\frac{1}{2}}{5\frac{2}{4}}$ kms.
i.e., $\frac{88\times \frac{5}{2}}{5\frac{2}{4}}=\frac{44\times 5}{\frac{22}{4}}=(44\times 5)\times \frac{4}{22}$
$=\frac{44\times 5\times 4}{22}=40$kms
