Does anyone know what this means? do i have to do pages 7 and 10 or 7,8,9 and 10?

I think you are intended to answer questions 7 to 10 and 13 to 16 completely and submit (by text) the pages that contain the answers. It is confusing.

6 spoons of sugar for every 21 cups of flour

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."
