Independent: Amount of hours she works
Dependent: Amount of money she makes
Step-by-step explanation:

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
