Distance, Rate and Time — Quick Reference Cheatsheet
A focused companion to the main Distance, Rate and Time topic page on SAT Math.
SAT Math Algebra One-page reference
This is a one-page reference for Distance, Rate and Time on the SAT math section. Use d = rt and convert between average rate, total distance and total time. Use it as a printable cheatsheet before test day, or as a refresher right before you attempt the worked questions on the main Distance, Rate and Time topic page.
What this topic is
A Distance, Rate and Time question on the Digital SAT tests your ability to manipulate linear relationships symbolically and verify your answer by substitution. The skill underlies roughly a third of every SAT math section.
Core formulas you must memorise
- Slope: m = (y₂ − y₁)/(x₂ − x₁)
- Slope-intercept: y = mx + b
- Point-slope: y − y₁ = m(x − x₁)
- Standard form: Ax + By = C
- Distance: d = √((x₂−x₁)² + (y₂−y₁)²)
If any of these formulas are not yet automatic, drill them via the Algebra formula sheet. Memorisation is fastest when you write each formula out by hand five times in a row, then quiz yourself the next morning.
How to spot this question type on the test
SAT questions on Distance, Rate and Time typically present in one of three ways: as a pure symbolic problem ("solve for x"), wrapped in a word problem (a real-world scenario you must translate), or hidden inside a longer multi-step question where Distance, Rate and Time is just the first or last step. Train yourself to recognise the signature — a particular word, equation form, or diagram — and you will halve your reading time.
The 30-second decision
Always isolate the variable using the same operation on both sides. Verify by substitution before locking in your answer choice.
If you have 60 seconds before the question
Glance at the answer choices first. If they are widely spaced, estimate; if they are close, you must be exact. Sketch any diagram involved. Identify which of the formulas above applies. Then attempt — and if you cannot finish in 90 seconds, mark and move on. There is no penalty for guessing on either the SAT or the ACT, so always bubble in.
