Hi, I am trying to work out what is the cheapest way to drive the two cars we have in our family - but I don't know what to do with the figures I have. Do I divide them? Multiply them? I have no idea!
What I am trying to do is to find out how much 1000 driving miles would cost with these three driving formats:
- Diesel car. It's average consumption is 46.7 mpg. I pay 1.55 per litre for its diesel.
- Phev car. It achieves 42mpg on it's 'hybrid' mode when it using petrol + electric. It's petrol is 1.46 here.
- Same phev car. It can use its pure-electric mode. It costs me £3.27 to charge it fully (I have one of those plugs that calculates this for you) which gives me 39 miles of driving.
Can someone please (pretty please) do the sums so I work out how much each of these three ways costs me to drive?
Many thanks
