\(average=\frac{22.5 \ miles}{1 \ gallon}=\frac{22.5*1.6 \ kilometers}{3.8 \ liters}=\frac{36}{3.8}\approx{9.5}\) (22.5*1.6 is ~40 and 3.8 is ~4 so the result must be ~10).

22.5 miles is 22.5 x 1.6 = 36 km.

1 gallon is 3.8 liters.

So the approximate rate, in km/liter, is 36/3.8 = 9.473.

\(\frac{22.5 }{ 1 gallon} = \frac{1.6 killometers }{ 1 gallon} = \frac{1 gallon}{3.8 liters}\) = \(\frac{20 * 2 }{4} = 10\)

Answer is B.

How can I calculate 22.5 * 1.6 quickly?
I did (225 / 10) * (16 / 10) = (15 * 15 * 16) / 100 thinking this was the quickest way but it took me long to multiply 225 * 16 (could not do the calculation in my head).


Thank you :)
