You can put this solution on YOUR website! Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to the time spent on weight training was 3 to 2. How many minutes per week did she spend on aerobics? How many minutes per week did she spend on weight training?
------------------
3:2 is the same as 3x:2x where 3x is time spent on aerobics.
------------
Equation:
3x + 2x = 250
5x = 250
x = 50
-------------
3x = 150 minutes (time spent on aerobics)
2x = 100 minutes (time spent on wt. training)
