Question

Convert the (US) price of gas of $2.26/gallon into (British) ₤/L. Hints: 1 ₤ = $1.35; 1 gallon = 3.785 L.  Do not include units in your submitted answer.

Answer 1

This problem is just a unit conversion problem.

I like to set mine up in table sometimes, especially if there are a lot of conversions involved.

We have the US price of gas at $2.26/gallon.

We need to convert the price into pounds. Since $1.35 = 1 £, we have to divide the price by 1.35 in order to convert from dollars to pounds.

2.26 / 1.35 = 1.67 £/gallon

Now we have to convert from gallons to liters. 1 gallon = 3.785 L. In order to convert from gallons to liters, we have to divide the price by 3.785.

1.67 / 3.785 = 0.441 £/L

I hope this helps!
