1 A motorcycle was purchased 5 years ago for $16,200. The current value of the motorcycle is $10,600. By how
much did the motorcycle decrease in value per year, on
average, over the five-year period?
A. $5,600
B. $2,720
C. $1,350
D. $1,120
E. $1,080

$1,120 each year

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."

answer: you need to organize this better it does not make sense.
