This question requires you to understand that T and J are coming closer and closer together, covering 105 km together in one hour. After an unknown amount of time, when they do meet, they would’ve covered 210 km together. Just use a simple equation and we obtain 2 hours. Then, use timeline to get 3 pm as the answer.
