Question

A car runs 18 km using 1 litre of petrol. How much distance will it cover using 2 1 by4 liters of petrol.
​

Answer 1

Answer:

40.5 km

Step-by-step explanation:

distance covered by car with 1 ltr petrol = 18km

=> dist. covered with 2$\frac{1}{4}$ ltr of petrol = 18 * 2$\frac{1}{4}$ km

                                                           = 18 * $\frac{9}{4}$ km

                                                           = 9 * $\frac{9}{2}$ km

                                                           = $\frac{81}{2}$ km

                                                           = 40.5 km
