In fifteen minutes, greg's sailboat went 3/6 mile, gina's sailboat went 6/6 mile, and stuart's sailboat went 4/6 mile. whose sailboat went the longest distance in fifteen minutes?

To make this situation easier to understand, you must simplify these fractions.  3/6 is equal to 0.5
6/6 is equal to 1
4/6 is equal to 0.3333 repeating.

With this info we can tell that Gina's sailboat went to longest distant in the fifteen minutes.

Hope this helps! :)
