Two students in the same Spanish class, Jessica and Eva, plan to get together after school to make vocabulary flashcards. Jessica started on the project yesterday and has already made 6 flashcards. Eva hasn't started yet. Since Jessica makes 4 flashcards per minute and Eva makes 7 flashcards per minute, Eva will soon have the same number of flashcards. How long will that take? How many flashcards will each student have at that point?
