Question

The data in Light-Duty Vehicles (1975–2006) show the efficiency of light-duty vehicles from 1975 (leftmost point of the connected line) to 2006 (rightmost point of the connected line). Each point represents a year in chronological order from the left end to the right.

Answer 2

• What generalizations can you make about changes in vehicle efficiency (horsepower multiplied by MPG) over the course of the study?

Answer 3

@Somy

Answer 4

all i see is that the overall i see in the beginning it was less efficient in both horsepower and MPG, then its efficiency increased drastically mostly with it's horsepower
so horsepower seems to be the main difference between 1975 and 2006

Answer 5

alright so then I would multiply by all the MPG values I've got?

Answer 6

yeah do you can do it if you want to see more details
to have a conclusion on this graph that is

Answer 7

would you have done that or is there an easier way?

Answer 8

i did do it, but i only did it with the drastic changes http://prntscr.com/9o5esl

Answer 9

oh ok alright thank you :)

Answer 10

but im not really a physics person so you can ask someone more qualified just in case :)
no problem tho)

Answer 11

nah I trust your opinion you have been helping me for a very long time :)

Answer 12

aw thats nice of you :D
