how do I set up this word problem? Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. How many minutes does she spend per week on each?

3x + 2x = 250 5x = 250 x = 50 so 3x = 150 minutes on aerobics and 2x = 100 minutes on weight training

It is not 3/2 = 250/x that would be if it said she spent 250 minutes doing aerobics
