Question

what is the speed of the train between points c and d on the distance - time graph? speeding up more and more slowing down more and more constant speed, faster than between points a and b constant speed, slower than between points a and b

Explanation:

Step1: Analyze the nature of the graph between C and D

In a distance - time graph, a straight - line segment indicates constant speed.

Step2: Compare the slope between C - D and A - B

The slope of a distance - time graph gives the speed. If the slope of the line segment between C and D is less steep than that between A and B, the speed is slower.

Answer:

constant speed, slower than between points A and B
