What is the relationship between rational numbers and integers?
rational numbers are a subset of integers because all rational numbers are integers.
there is some overlap between rational numbers and integers, but there are numbers that are just rational and numbers that are just integers but not both.
there is no relationship as there are no overlapping numbers.
integers are a subset of rational numbers because all integers are rational numbers.

  Integers are a subset of Rational Numbers because all Integers are Rational Numbers.

Step-by-step explanation:

A rational number such as 4/2 is also an integer: 2. A rational number such as 4/3 is not an integer. Hence, integers are a subset of rational numbers.

what is the image?

- "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."
