The graph of the relationship between the time a train travels and the
distance it travels at a constant speed would be a
graph.

• is the distance,
• is the constant speed,
• is the time.

Explanation:

1. Linear Relationship: The equation indicates that distance is directly proportional to time when speed is constant. This means that as time increases, distance also increases linearly.
2. Graph Characteristics:
   • The x-axis would represent time ( ).
   • The y-axis would represent distance ( ).
   • The slope of the line would be equal to the constant speed ( ).
   • The line would pass through the origin (0,0) since if no time has passed, no distance has been traveled.
