Robert is writing a paper for language arts class. he can write 2/3 of a page in 1/2 of an hour. at what rate is robert writing?

page/hour

Step-by-step explanation:

Robert is writing a paper for language arts class.

He can write of a page in   hour.

He can write in one hour =

                                         =   ×  

                                        =  

                                        =   page/hour

Robert is writing   page per hour

chase is right because he already been to the swings and he know how far it will be to get there

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."
