Question 242526
<font face="Garamond" size="+2">

You can set up the proportion the same way, just do the division first.  Not that it matters much.  You still end up doing the same arithmetic.


The only way to solve it without using some form of the manipulations of cross-multiplication is to not use algebra at all.  You go find the motorbike that you know can run 10 minutes on $1.30, put $0.91 worth of gas in the tank that you have previously emptied, and then time how long the bike runs.
