Question

Mr. Brady's new car get sixty miles to the gallon. In the metric system gas consumption is measured in liters per 100 kilometers, how do you make the conversion?

Answer 1

Gas consumption is `100` kilometers to `3.92` liters

Explanation:

To convert gas consumption from miles per gallon to liters per `100` kilometers, we should first know

(1) the relation between gallon and liters - this is `1` gallon is equal to `3.78541` liters and

(2) relation between miles and kilometers - this is `1` gallon is equal to `1.60934` kilometers.

Hence `60` miles to `1` gallon is equivalent to

`60xx1.60934` kilometers to `3.78541` liters

or `1` kilometers to `3.78541/(60xx1.60934)=0.0392` liters

or `100` kilometers to `0.0392xx100=3.92` liters
