Question

the speed of sams car over time. speed of car time (hours) which best describes what is happening in section c? ○ his car is stopped. ○ his car is speeding up. ○ his car is slowing down. ○ his car is traveling at a constant speed.

Explanation:

In a speed - time graph, the slope of the line represents the acceleration (or deceleration). In section C, as time increases, the speed is decreasing (the line has a negative slope). If the speed was constant, the line would be horizontal. If it was speeding up, the speed would increase with time. If it was stopped, the speed would be 0. So the car is slowing down.

Answer:

His car is slowing down.
