Explanation:

Step1: Analyze the distance - time graph for segment EF

In a distance - time graph, the slope of the line represents speed. If the slope is constant (a straight line), the speed is constant. If the slope is zero (horizontal line), the object is at rest. If the slope is negative (line going downwards from left to right), the object is moving back towards the original position.
For segment EF, assume it is a straight line with a constant negative slope. A constant slope means constant speed, and a negative slope means moving back towards the original position.

Answer:

fast constant speed, moving back to the original position
