An electric car has a usable battery capacity of 31.3 kWhr which can supply a range of 134 miles. A comparable petrol car has a mileage of 30.1 miles per gallon (take 1 gallon to be 4.546 litres). It costs 15.7 pence/kWhr to recharge the car from the plug, and £1.28 per litre for petrol. What is the running cost of the electric car? pence/mile What is the running cost of the petrol car? pence/mile ) If the electric car costs £5500 more to buy than the petrol car, how many thousand miles does the owner need to drive for the overall cost (purchase price plus running costs) to be the same? thousand miles
