Question

(b)Dan leaves his house on his bike. He rides at a constant speed until he reaches a lemonade stand, where he parks his bike and takes a rest. Then he turns around and bikes home as fast as he can.

Answer 1

Answer:

The correct answer is the second graph.

Explanation:

Dan leaves his house at a constant speed. Then, the time starts counting, and his graph is a line that starts in (0, 0)

Then, he stops, we can see this part in the graph constant. Because he is not moving, the distance from his house remains the same.

Finally, goes back and we can this as a line. Since he is going at a faster speed, the line is more steep.

This is what we can see in the second graph
