Question 103899
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 per week does she spend on aerobics? How many minutes per week does she spend on weight training
-------------------
3:2 means the same as 3x:2x where 3x is aerobics time and 2x is weight training.
EQUATION:
3x + 2x = 250
5x = 250
x = 50
---------------
aerobics time = 3x = 3*50 = 150 minutes
weight train time = 2x = 2*50 = 100 minutes
