Lesson details
Key learning points
- Average speed can be calculated by dividing the distance travelled by the time taken.
- The units for time and distance determine the units for speed.
- By rearranging the formula, you can calculate either distance or time.
- Pace can be calculated by dividing time taken by distance travelled.
Keywords
Speed - Speed is the rate at which something is moving. It is measured as the distance travelled per unit of time.
Pace - Pace is the rate of movement. It is measured as the time taken per unit of distance.
Common misconception
E.g 4.5 hours is 4 hours and 50 minutes
Encouraging pupils to use ratio tables to represent proportional relationships using minutes allows them to appreciate the multiplier of 60 when converting hours to minutes, or minutes to seconds.
Encouraging pupils to work in minutes rather than hours will help to overcome the misconception.
