Question 442529
Kay spends 250 min/wk exercising. Her ration 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?
----
aerob/wttr = 3/2
------
3:2 is the same as 3x:2x
-------------------------------
3x + 2x = 250
5x = 250
x = 50
----
aerob = 3x = 3*50 = 150 minutes
wttr = 2x = 2*50 = 100 minutes
