The lowest graph is the answer. Why? Well, the others are incorrect because:
The 1st graph would represent a scenario where on the way home from school, Angelo is idle somewhere and then walks home at a faster rate than he did to school.
The 2nd graph would represent a scenario where Angelo walks at a faster pace to school than he does back home.
The 3rd graph would represent a scenario where on the way to school, Angelo becomes idle for a bit and then continues to walk to school at the same pace.
Meanwhile, the 4th graph represents Angelo walking to school, staying at school for a while, and then walking back home at a faster rate (possibly running).
Your final answer: The bottom graph is the correct answer. If you need help, let me know and I will gladly assist you.
