Answer 1

`Cost = 112.266` cent/km

Explanation:

Given

`Unit\ cost = R17.82/litre`

`Rate = 6.3litre/100km`

Required

The fuel cost in
`cent\ per\ km`

This is calculated using:

`Cost = Unit\ cost * Rate`

`Cost = R17.82/litre * 6.3litre/100km`

`Cost = R17.82 * 6.3/100km`

`Cost = R1.12266/km`

Multiply by
`100` to get the cost in cents

`Cost = 1.12266 * 100` cent/km

`Cost = 112.266` cent/km
