Perform each of the following operations and answer these questions: What does each resulting equation look like? Is it still a true equation? Show your work on each step. Add 12 to each side of the equation. Add 10+2 to the left side of the equation and 12 to the right side. Add the equation 4+3=7 to the equation 50+1=51.

- "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."
