Question 167768
Note: 1 hr = 60 min


So if the "teacher requires that students devote no less than 1 hour a day to their homework assignments", this means that the number of minutes 'm' a student should spend per <b>day</b> is {{{m>=60}}} (so they should do homework for 60 or more minutes)



Now since there are 7 days in a week, this means that you simply multiply 60 by 7 to get {{{60*7=420}}}



So the inequality becomes {{{m>=420}}} which means that students should spend at least 420 minutes a week doing Spanish homework.
