Question

2. A car has a fuel tank that holds 45 liters of fuel. The car consumes 8.0 liters of fuel for

each 100 km driven. A trip of 350 km was started with a full tank of fuel. How much
fuel remained in the tank at the end of the trip?

Answer 1

Answer: 17 liters

Explanation:

Make a proportion:

100 km - 8 liters

350 km - x liters

Hence,

`\displaystyle\\x=(350*8)/(100) \\\\x=(2800)/(100)\\\\x=28\ liters \\\\45-28=\\7\ liters`
