How do you solve this?

x is equal to 12.

Step-by-step explanation:

Because the two lines are parallel to each other, and one is the base of the triangle, that means that the segments of the side lines have the same ratio to each other.

In other words, |AC| / |CE| is equal to |AB| / |BD|.

With that information, we can simply say:

So x is equal to 12

- "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."
