004 It takes Jinny 56 minutes to drive to her friend's house.She drove 15 minutes and then stopped at a store.She then drove another 10 minutes.What do you need to do to find the amount of time she has left to drive?

You add the time she already drove (15+10) and get 25

56-25 = 31 minutes left.
Now if the 56 minute trip includes the stop at the store, we are OK with that answer.  If not, then we have to know how long she stopped at the store and add it onto 31 minutes.
