Core concepts
Concept 1
A rate relates two quantities and must retain both units.
Exam cue: Write the rate as a labelled fraction before rearranging.
Concept 2
Multi-stage problems may change rate, duration or unit midway.
Exam cue: Build a short timeline for journeys or staged processes.
Risk pitfalls and guardrails
Mixing minutes with hours in the same formula.
Guardrail: Do not use obsolete Abstract Reasoning material or convert practice accuracy into an invented official scaled score or SJT band.
Averaging rates without weighting by time or distance.
Guardrail: Do not use obsolete Abstract Reasoning material or convert practice accuracy into an invented official scaled score or SJT band.
Memory anchors
Label the Rate
Keep both numerator and denominator units visible.
Convert Before Combine
Use one time or measurement unit throughout.
Distance Triangle
Distance equals speed multiplied by time.
Timeline
Split journeys and staged processes into clear intervals.
Weighted Rate
Overall rate depends on total quantity divided by total time.
Direction Check
Confirm whether the conversion multiplies or divides.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
