I won't answer the questions for you, but I'll translate what they mean (if you still need help after this, leave a comment (: )
1.) At what hour do they leave the house? (3:00) 2.) What do Inés and Cecilia see? (shoes) 3.) Where did Inés lose the money? (In the sports shop) 4.) Did you return to the store to look for it? (Yes)
(Not sure how well I did on 4, If I remember right "buscarlo" is an example of a reflexive verb.)
Answer: To tell time, state the number of minutes first, followed by the number of minutes until a certain hour, and then the number of minutes after the hour. In some countries they will leave the out the 'y' and in some countries they will use 'e' instead of the y.
