0.109.2 x 94.22 = 10.29 cents

(iii) 1.2 x 1000 = 1200 1200 x 15 = 18 000

(iv) 10 hours = 600 minutes, 18 000 / 600 = 30 drops per minute

[kkorpz]

geez.. u screwed up this question? this question was too easy.. there were other ones that were harder than this one..

 

[Benovista]

yeah whats a kilolitre? That was the only question i think i got wrong... judging from above answers

 

[Dammit]

1 kilolitre = 1000 Litres

Simpsons rule, the answer should be between about 48 and 52. remember its an Approximation.

Those sorts of questions such as in a. are always a weakness for me. (conversion of litres into minutes, etc etc)
You found the others hard? geez...they were too easy
