Distance problems 11 plus: clear steps for parents
21 October 2026
Understanding distance problems
Distance problems are a common feature in 11+ maths exams, especially in the CEM and GL styles. These questions ask pupils to calculate how far something travels, how long it takes, or the speed involved.
Key insight: use the speed-distance-time triangle
The speed-distance-time triangle helps children remember the relationships between these three values. Cover the value you want to find. For distance, multiply speed by time. For speed or time, divide as needed. Always check that the units match before calculating.
Common mistakes to avoid
Many children lose marks by mixing up units. If speed is in kilometres per hour but time is in minutes, convert time to hours before multiplying. Remind your child to read the question carefully and underline the units.
Worked example
A cyclist travels at a speed of 12 km per hour for 3 hours. How far does she travel?
Step 1: Write down the formula. Distance = Speed × Time.
Step 2: Check the units. Both speed and time are in hours, so no conversion is needed.
Step 3: Multiply the speed by the time. 12 km per hour × 3 hours = 36 km.
The correct answer is 36 km.
Supporting your child at home
Encourage your child to practise different types of distance problems, including those involving unit conversions. Use real-life examples, such as journeys by car or bicycle, to make the questions more relatable.
