Question

The graph shows a proportional relationship between time and the number of boxes a machine packages. How many boxes does the machine package in 5 minutes? your graph: (write down) Y axis number of boxes, 0- - 120- - 240- - 360- - 480-. X Axis Time (minutes), 0- - 2- - 4- - 6- - 8-.

Answer 1

Accroding to the graph.:
0 min     0 boxes
2 min     120boxes
4 min     240 boxes
6 min     360 boxes
8 min     480 boxes.

So 2 minutes "gives us" 120 boxes
120/2= 60 boxes per minute.
In 5 minutes the machine package does 5*60=300 boxes.
