  6. 1. It's a good idea to inform the viewer the information given at the start.

    2. The diagram encapulated all the given information :)

    3. Explanation to (a) is very clear, except last part, the unit is not articulated.

    4. You've pointed out how we could make use of the unit given as a clue to find the rate. Good :) This is because "Rate" of petrol consumption can be interpreted differently too.

    5. For (c), you have articulated how to solve the problem very clearly and systematically.

    6. This is a good attempt, and we follow the flow of explanation.

    7. For distance, read as "kilometres" instead of "k""m"; also, for (c), say "2 and a half" instead of "two one two"

    8. Visual: It's a bit blur and we can see the reflection of the learning device (?)
