Math CentralQuandaries & Queries


Question from Casey, a student:

I have to write a variable equation. The questions says there are 60 seconds. but we need to write and equation to solve for minutes. Is it 1/60 or 1/s


Neither of these is an equation - an EQUAtion is s statement that two things are EQUAl.

If you're trying to solve for one thing, you want it to be alone on one side for the equals sign.

So your answer should start with something like

M = [some expression involving S]

where M is the number of minutes, S the number of seconds.

Now, if S was 60 (sixty seconds), what would M be (how many minutes?)

Good hunting!
