Lizzy: Janice needs to go to watch a movie in 2 hours. before she could leave, she needs to finish her homework which takes 30 minutes; clean her room which takes half as long as her homework; walk the dog which takes 5 minutes more than making homework; take out the trash which takes 1/6 of the time it takes her to do the homework. How many more minutes do Janice have left before the movie starts?.
Me: Hmmm, let me think. I think this is the detailed solution:
Janice takes 30 / 2 = 15 minutes to clean her room. It takes 30 + 5 = 35 minutes for her to walk the dog. It takes her 30 x 1 / 6 = 5 minutes to take out the trash. So, it will take 30 + 15 + 35 + 5 = 85 minutes to do all those chores. Since there are 60 minutes in 1 hour, then 2 hours is 2 x 60 = 120 minutes. Thus, Janice still has 120 - 85 = 35 minutes left before the movie starts. Final answer: 35.
