Question

Philip takes his car on a trip with `3` friends to Disneyland. His car consumes `50` liters of fuel for `500km.` Journey to Disneyland and back is `4000km.` and fuel is `$1.35` per kilometer. If the bill is split between them, how much each of them pays?

Answer 1

Each of them pays `$135`

Explanation:

For `500` `km.` car consumes `50` liters

Hence for `1` `km.` car consumes `50/500=1/10` liters

and for `4000` `km.` car consumes `1/10xx4000=400` liters

As `1` liter costs `$1.35`

`400` liter costs `$1.35xx400=$540`

As Philip is going on a road trip with three of his friends to Disneyland, this should be split between `4` persons

and hence each of them pays `$540/4=$135`
