Students deliver catalogues (c) and leaflets (l) to houses. one day, they have to deliver 360c and 1440l. each student can deliver either 15c or 80l in 1 hour. each student's can only work for 8 hours. work out the minimum number of students needed.

To determine the minimum number of students needed to deliver catalogues, you will divide the total number of catalogues by (15 per hour x 8 hours) 90 catalogues to find how many students per day are needed to deliver these.

360/90 = 4 students.

To determine the minimum number of students needed to deliver leaflets, you will divide the total number of leaflets by (80 per hour x 8 hours) 640 leaflets to find how many students per day are needed to deliver these.

1440/640 = 2.25 or at least 3 students

4 students + 3 students = 7 students.

You will need 7 students minimum.
