    Let A and B represent the number of hours that plans A and B last, respectively. Then the problem statement tells you

    7A + 9B = 12

    5A + 3B = 6

    There are many ways this set of equations can be solved. I find it fairly simple to use a graphing calculator. The one shown tells me the workouts are each 3/4 of an hour.

    Plan A lasts 45 minutes (3/4 hour)

    Plan B lasts 45 minutes (3/4 hour)
