On saturday, the gomez family left home to a resort in maine. the drove at an average rate of 48 mph. on thursday they went back home traveling at an average speed of 40 mph because of work construction. if the gomez family spent 11 hours driving to and from the resort in maine, how many miles did they travel from their house to the resort? show work!

- "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."
