Idk how fast alejandra drove, all i know is that she drove 70

  980 miles

Step-by-step explanation:

If Alejandra averaged 70 mph for the trip, she drove 70 miles for each of the 14 hours, or ...

  (14 h)(70 mi/h) = 980 mi

Her total distance was 980 miles.

Comment on speed limit vs average speed

You are correct in your assessment that you need to know how fast Alejandra drove. Since that is not given in the problem statement, assumptions are required. I expect the assumption is supposed to be that her speed was at the speed limit.

In my experience, the average speed for a trip is 10-20 mph lower than the speed limit, due to stops for gas and eating. This problem statement seems to only count driving hours, so perhaps her average speed is very near the speed limit.

Though illegal, it is also not unusual for drivers these days to drive 5-10 mph over the speed limit. The "flow of traffic" is generally recognized to be 7 mph over the speed limit for speed limits above 30 mph.

idk the answer but just put a

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
