Edexcel IGCSE Maths 复习笔记 3.3.1 Distance-Time Graphs
What is a distance-time graph?
- Distance-time graphs show distance from a fixed point at different times
- Distance is on the vertical axis, and time is on the horizontal axis.
- The gradient of the graph is the speed:Speed =RISE / RUN=DISTANCE / TIME
- Straight line = Constant speed
- Horizontal line = Stationary (not moving!)
Exam Tip
It is easy to get confused between different types of graph.
Look at the label on the vertical axis to make sure you are looking at a DISTANCE-time graph (not speed-time).
