  1. 1. It's a good idea to inform the viewers what the question is at the beginning.

    2. The use of diagram is useful as it allows us to lay out the information clearly.

    3. You have explained how you would approach (a) pretty clearly :)

    4. When you mentioned "40 min is none other than two third hour", it would be good to explain how you convert the time to another unit.

    5. Explanation of the steps to (a) is clear and systematic :)

    6. You've reminded the viewer that returned journey is moving from Q to P. Good.

    7. Explanation for (c) is very clear.

    8. The use of pen to guide the viewer on parts that you are explaining is good :)
