60x1000=60,000 (convert km into m)60,000/(60x60)= 16.67m/s (here we divide the 60,000m by the number of seconds within an hour, which is 3600)Final answer is therefore 16.67m/s

Use the 'crab claw' technique for which order to expand your brackets in (demonstrate by drawing with whiteboard). So start with 2x multiplied by x = 2x^2. Then 2x multiplied by 3 = 6x. Then 4 m...

So with these kind of questions they tend to be more of a first part to a question, probably worth about two marks on an A Level exam.The first thing to spot with this question is that f(x) contains a pro...

So to get 11 you could roll a 5 and a 6 or a 6 and a 5.Probability of rolling 5 and 6 = 1/6 x 1/6 = 1/36Probability or rolling 6 and 5 = 1/6 x 1/6 = 1/36So probability of rolling an 11 is 2/36

Here I would include all the working out. If the question was different, I'd also draw more diagrams and illustrate the question better, as I believe it's easier to remember and understand that way.x = 5y...
