Compound Measures (Speed, Density, Pressure) | 40 Worked Examples | Edexcel GCSE Higher Maths

40 progressive Edexcel GCSE Higher (1MA1) compound measures questions with full mark-scheme style worked solutions. Every line is explained and every mark is annotated at the exact point it would be awarded.

What’s inside:
Easy: using speed = distance / time, density = mass / volume and pressure = force / area, plus rearranging each formula to find distance, time, mass, volume, force or area, with correct units throughout.
Medium: unit conversions between m/s and km/h, converting minutes to hours, and finding average speed across a simple two-stage journey using total distance over total time.
Hard: the classic average speed trap (why you cannot average the two speeds), converting g/cm^3 to kg/m^3, finding the combined density of a mixture of two materials, pressure problems requiring a cm^2 to m^2 area conversion, and worded multi-stage journeys.

Every solution breaks the work down one step at a time, with the reasoning spelled out in plain English and the common pitfalls (especially the average speed trap) made explicit. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 10 and 11 students sitting Edexcel GCSE Higher Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
