easy shit[/Q
really mine was bad for the first question i wrote 600/x+20 and the quadratic thing i didnt get and what was you last answer the total rate of litres used thingy?

 

[chum1234]

they asked complete journey yeah ?
so both the 600/80 you need to consider the 600/80+20 also

I got 13.5 .... i added 7.5 and 6 :S

Guys how did u show that quadratic eq thing ?? 600/x+20 -1.5 ??

that took me time! but i got it
600/x - 600/x+20 = 1.5 then simplify forward and divide by 1.5
