k, I'm going to go read the tutorial, then come back and try something else out.
ok, lets try posting with fractions Simplfy assuming M drives 400 in one hour less than J. If M's speed is 20 km/h faster than J's, what is the proper equation to determine the speed of J?

So, ?

Originally Posted by Quick yes, I'm glad you realized that, it should be written as, though I don't see why any one form should be more "correct" than any other. As far as I know there is no consensus on any particular form. Also, Quick: Why do you keep using " " as opposed to simply "-"? -Dan

Also, Quick: Why do you keep using " " as opposed to simply "-"? -Dan I think they are looking for simplest form... BTW: I am starting to use the for negative numbers, particularly fractions.
