Knowledge points:

E1.11.1 Demonstrate an understanding of ratio and proportion. (To include numerical problems involving direct and inverse proportion.)

E1.11.2 Increase and decrease a quantity by a given ratio.

E1.11.3 Calculate average speed. (Use ratio and scales in practical situations.)

E1.11.4 Use common measures of rate. (Formulae for other rates will be given in the question e.g. pressure and density.)

E5.1 Use current units of mass, length, area, volume and capacity in practical situations and express quantities in terms of larger or smaller units. (Convert between units including units of area and volume.)
