The distance-time graphs shown represent the motion of a car. Which of the following graphs represents the car at constant speed?

• graph A
• graph B
• graph C
• graph D

The following graph is important in explaining?

• Distance vs Time Graph. This graph can represent motion within object by identifying if an object is in motion, or not in motion.
• Speed vs. Time Graph. This graph can represent motion within object by identifying if an object is in motion, or not in motion.
