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 butyou have to pay for the fuel that you use.

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?

  • The Hire company has only provided basic information for 3 different cars:

  • 1) How much fuel they use in urban areas

  • How much fuel they use on motorwaysInformation is in Miles per Gallon (mpg)

Distance to Concert cheapest to re-fuel after the trip.

Woodbridge to London

Built up area (Urban) 15 miles

Motorway (A14 & M25) 65 miles

Diesel 110p per litre

Petrol 104p per litre

40

4.5

To convert fuel consumption from gallons to litres

= 8.89 miles per litre (to 2 d.p.)

40 mpg is equivalent to miles/litre

1 Gallon ≈ 4.5 litres
