Question

Ipsa bought a car which covers 363 km in 24.2 liters of petrol. One day, she has to go to airport but in her car there was only 7 liters of petrol, how far can she go?

• A. 86 km
• B. 105 km
• C. 67 km
• D. 213 km

Answer 1

The correct option is B

105 km

Given: Distance traveled in 24.2 liters of petrol = 363 km
To find : Distance traveled in 7 liters of petrol.

$\text{Since, Distance travelled(y)}$$\propto \text{Amount of petrol used (x)}$

$\frac{x_1}{y_1}=\frac{x_2}{y_2}$

$x_1=363km{y}_1=24.2l{y}_2=7l{x}_2=\text{Distance travelled in 7 liters}\text{of petrol}$

On substituting the values, we get

$\frac{363}{24.2}=\frac{x_2}{7}$

$x_2=\frac{363\times 7}{24.2}$

$x_2=105km$
