Objective: To explain relation between speed, time and distance
Subtopics to be covered:
- Direct proportion relation between change in distance affecting change in time
- Speed = Distance/Time
- Simple word problems on speed
Learning Outcome:
- Students can solve word problems and find speed taken to cover a distance
- Students can solve word problems to find distance covered if speed and time given
- Students can solve word problems to find time taken to cover a distance if speed is given
