Rachelle spends 330 min/wk exercising.
Her ratio of time spent on aerobics to time spent on weight training is 6 to 5.
------
6 to 5 is the same as 6x to 5x, where 6x is aerobic time and 5x is weight
training time.
-------------
How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?
------
Equation:
6x + 5x = 330 min
11x = 330
x = 30 min
----
6x = 6*30 = 180 min (aerobic time)
---
5x = 5*30 = 150 min (exercise time)
