### Math Viva Question #8

Sorry if late... and also i din see the examples before i did this viva and i was at my grandmother house tonight so i decided to use the white board immediately when i reached home. I only posted once i reach home after my grandmother house trip ._.

Owen here btwfyi...

1. i think i over exceed the time also DD: maybe i shouldn't talk that much :X

2. Presentation:
> Alignment of Explanation with Visuals (1)
> Clarity of Voice/Volume (1)

Explanation:
> Mathematical Terms (1)
> Explanation of working/solution must be clear (2) The timeline is a little messy...
> Understanding of concepts (2)
> Accuracy of answer (1) Where did all your units go? 360/4.5≠80km/h Same case for your part B

3. lol that 360/4,5 = 80km/h is actually can de cos i wrote before in the math and science exam and never got deducted...

4. i dunno so much i only pointing out its mathemathically wrong idc bout ur exam marking also...

5. Presentation [1]
Noisy background, blurry, voice not clear.

Explanation:
> Mathematical Terms (1)
> Explanation of working/solution must be clear (2) The timeline is a little messy.
> Understanding of concepts (2)

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 (?)
