This sentence is key: "At this point, he is 3 blocks from school and half way there"
<span>since 3 blocks is halfway of the trip, that means the total distance is 6 blocks </span>
<span>from the stoplight to the library must be one block, and one block took him 4 minutes </span>
<span>therefore, therefore, the total trip takes 4 * 6 = 24 minutes, or 4 * 3 = 12 minutes from the library </span>
<span>8:24 + 12 = 8:36 </span>
<span>he arrives at school at 8:36 </span>
<span>(and yes, make sure to sketch this out!)</span>
