Ling wants to determine the average distance she travels each day in her car. She will use the odometer in her car to collect information because it measures the total distance her car has been driven since it was
made. She decides to record the odometer reading each morning before driving it for the day. Below are the
readings for each morning. (NOTE: the odometer does not start back at 0 each day. Instead it is a running
tally of the total distance the vehicle has been driven since it was made.)
Day 1 2 3 4 5 6 7
Odometer (mi) 10,150 10,211 10,424 10,769 10,884 11,155 11,477
What is the mean distance Ling travels each day? Show your work.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

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."

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )
