The distance versus time graph for object a and object b are shown. which object moves with changing speed?

Both: Object A and Object B, because different distances are traveled in the same time interval

Explanation:

Constant Speed Motion

An object is said to have constant speed it travels same distances at the same time intervals. For example, an object who travels 4 meters in 2 seconds has a constant speed if it also travels 6 meters in 3 seconds and 10 meters in 5 seconds. The constant speed is 2 m/s.

We can see in the image provided two graphs of distance vs time of two objects. If they were traveling at a constant speed, that graph should be a single line (increasing, decreasing of horizontal). None of the graphs show a line, which indicates the object some times travels more or less distance in a given time interval than in other equal time intervals. Thus, the answer is the last option:

Both: Object A and Object B, because different distances are traveled in the same time interval

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
