Petrol Stations display prices using digital numbers. These are made up of small line segments. What is the largest number you can make with 10 segments? What is the largest number you can make with 16 segments?
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?
Diesel 110p per litre Petrol 104p per litre Distance to Concert Woodbridge to London Built up area (Urban) 15 miles Motorway (A14 & M25)65 miles To convert fuel consumption from gallons to litres = 8.89 miles per litre (to 2 d.p.) 40 4.5 40 mpg is equivalent to miles/litre 1 Gallon ≈ 4.5 litres
