    I am having a problem with a question, I am wondering if anyone can help me with it.
    A man jogs at a speed of 1.5m/s. His dog waits 1.6s and then takes off running at a speed of 3.8m/s to catch the man. How far will they have each traveled when the dog catches up with the man? Answer in units of m.

    You need to show some work before we can help you. As a hint, what quantity must be the same for both the man and the dog when the catches the man up?

    No. Think about it like this. Imagine you are walking down the street and your dog is following you. When it catches you up, you are both in the same ______.
