Question

You own a car that consumes diesel fuel at a rate of 6.7L/100km. On a 2500km trip to the East Coast you estimate that the average fuel price will be $0.93/L. What will your estimated fuel cost to drive the 2500km trip?

$\small{ \begin{array}{lcl} 2500\ km \cdot \left( \frac{6.7\ l}{100\ km} \right) \cdot \left( \frac{$0.93}{1\ l} \right)\\ &=& \dfrac{2500 \cdot 6.7\cdot 0.93}{100} \\ &=&$155.775 \end{array} }$

The 2500km trip will cost $155.78
