This topic covers the relationship speed = distance ÷ time, rearranging it, using consistent units and reading distance–time graphs. It's examined right across GCSE and iGCSE Maths. Learn it free on eClassroom through guided worked examples and instantly-marked exam-style questions.
How you do it
Speed is distance divided by time, and the triangle rearranges it for whichever you need. Convert units before you calculate — minutes to hours, metres to kilometres — and remember 1 hour 30 minutes is 1.5 hours, not 1.3.
Before you start
The groundwork here is the four operations and unit conversion. It is Foundation and Higher tier material at GCSE and iGCSE. It reappears throughout compound measures and rate problems.
What you learn
The three quantities — speed, distance and time — are linked by one formula, and a distance-time graph shows the whole journey at a glance. The three quantities are linked by speed = distance ⁄ time. On a distance-time graph, time is along the bottom and distance is up the side. Average speed = total distance ⁄ total time — including any time spent stopped. The course works through the speed formula, distance-time graphs and average speed and units. Every section has instant-feedback practice questions matched to Edexcel iGCSE 4MA1 and the other major GCSE boards, and the course finishes with full exam-style questions you mark yourself.
Related Topics
We teach Speed, Distance, Time as one of the Ratio and Proportion topics in our GCSE course library, at Foundation tier. The course is built from 3 concept sections, 2 worked examples and 3 check points before the exam-style set. Students often pair it with Unit Conversion, Compound Measures, Density & Pressure and Direct & Inverse Proportion. For unlimited practice, the Ratio and Proportion revision engine builds new questions on demand and records your accuracy.
