4. There are 4 cartons of orange juice in each package. If there are 79 cartons of orange juice, how many packages can be filled? 79 : 4 = So, packages can be filled.

The answer is 19.75 or 19 packs and one pack going to have 3 out of 4 cartons

Step-by-step explanation:

There are 4 cartons in each bundle, for a total of 79 cartons. You'd take 79 and split it by four to get 19.75. It would have been 20 if there were 80 cartons of orange juice.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
