Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight lifting is 3 to 2. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?
-----
3:2 is the same as 3x:2x where 3x is time lifting weights.
-------
Equation:
3x + 2x = 250
5x = 250
x = 50
-----
weight time = 3x = 150 minutes
