Answer: 16 minutes.
Step-by-step explanation:
Given that the:
Distance covered = 8 miles
And it took her to run each mile, rounded to the nearest 1/4 of a minute.
Since it is a minute ( 1 minute ), add 0.25 to 1 for the fastest and subtract 0.25 from 1 for the slowest.
That is, 1 + 0.25 = 1.25 for maximum time, and 1 - 0.25 = 0.75 for the minimum.
For the Army slowest , 8 × 0.75 = 6 minutes
For the Army fastest, 8 × 1.25 = 10
Amy runs her slowest and fastest mile combined by adding the value of the slowest to the value of the fastest.
10 + 6 = 16 minutes
9/5
If you choose two points you can find the equation change in y/change in x (y2-y1)/(x2-x1). Using the first two points this looks like:
(49-22)/(25-10)=27/15=9/5
