Draw a model to represent the following problem 12×6

We can model the problem in many different ways.

One example is to divide 12 counters (modelled as circles) into six boxes (modelled as square)

We have two circles inside each box

The model is shown in diagram below

Hope that help!

range is infinite on both x and y axis positive and negative

step-by-step explanation:

- "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."
