E is the midpoint of line DF and line BC. Angle ACB is congruent to angle BED. Prove ADFC is a parallelogram. (use proofs) this is geometry

you need to show us the graph.

- "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."

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
