Question

6/12
distance (meters)
30
20
10
0 1.0 2.0 3.0 4.0 5.0 6.0
time (seconds)
describe the speed of the object from 4-6 seconds using
constant speed
decreasing speed
increasing speed
not moving

Explanation:

In a distance - time graph, the slope represents speed. From 4 - 6 seconds, the distance remains 30 meters (the graph is horizontal), so the slope is 0. A slope of 0 means the object's speed is 0, i.e., it is not moving.

Answer:

D. Not moving
