Question

On an average tyrone's truck will travel 19 miles per gallon of gas. how many kilometers per liter of gas will the truck travel? round your answer to the nearest tenth.

Answer 1

Step One

Convert miles to km. The conversion constant is 1.6 km / mile

19 miles * 1.6 km/mile = 30.4 km Notice the miles cancel.

Step Two

Convert the gallons to liters.

This is the sticky part of the question. Where are you? The conversion factor is different in Canada or Great Britain that it is in the United States. If you are not in the US use 4.5 otherwise 1 gallon has 3.78 L in it if it is a US gallon

30.4 km / 3.78 L = 8.04 km per Liter using a US Gallon.

30.4 km / 4.5 L = 6.76 km / Liter using an Imperial Gallon which not used in either Canada or Great Britain. Imperial Gallons are obsolete.
