Sell-out Concert in London! Amazingly, you have managed to get tickets but you now have very little money left to get there. There is no public transport from Ipswich or Woodbridge to take you all the way there. Only option – you’ve hired a car! The only cars available are all the same price but you have to pay for the fuel that you use. Learning Objective: To use appropriate units of measure to investigate travel costs

The Hire company has only provided basic information for 3 different cars: 1) How much fuel they use in urban areas 2)How much fuel they use on motorways Information is in Miles per Gallon (mpg) We are going to investigate which car is going to be the cheapest to re-fuel after the trip. What information are we going to need so we can make an informed choice of car to hire?
