Facebook Live Coaching #22 – Rate
Thank you for your overwhelming response to my last Facebook live last week on the topic of Speed. Similar to speed, “Rate” is another topic that stump many children & parents alike!
The concepts on Rate and Speed are similar …
Speed refer to how fast an object moves.
Rate refer to fast an object changes.
The three common “rate” questions that appear in the exam:
(i) Working rate [how fast a person take to complete a job]
(ii) Water rate [how fast water flows in and out from a tank/tap]
(iii) Printing rate [how fast a printer print]
