ment 6 to this 2-3 S18> Due Sat 02/03/2018 4:59 am a. Which of the following variable definitions is appropriate for representing Stephanie's varying distance from the start of the race? (Hint: that whern you define a variable you need to include the attribute you are measuring, the reference point from where you are measuring, and the unit of measure.) -Tn represents the distance Stephanie ran Om represents the number of miles Stephanie has run since the start of the race Om represents distancoe Om represents number of miles b. Which of the following situations could represent m 7, assuming your definition of m in part (a)? Select all that apply. Stephanie has run 7 miles since she stopped for water Stephanie is 7 miles from the starting line Stephanie is 7 miles from the finish line Stephanie has run 7 miles since the half way point of the race None of the above Which of the following situations could represent m 11, assuming your definition of m in part (a)? Select all that apply. c "Stephanie has run 11 miles since the halfway point of the race Stephanie has run 11 miles since she stopped for water Stephanie is 11 miles from the finish line Stephanie is 11 miles from the starting line None of the above

Explanation / Answer

a)
Option B
This is the perfect option that talks about the total distance she has run sicne the start of the race

---------------------------------------------------------

b)
Option B
Previously we took the 'm' to be the distance from starting pt
So, option B indeedio!

----------------------------------------------------------

c)
Option B again
delta(m) = 11
This means, there was a distance m2 = 11 + a
And distance m1 = a
Distance m1 = a could have been her distance when she stopped for water
And m2 = 11 + a could have been her distance of 11 miles run after her stop for water

So, the difference m2 - m1 will represent the distance she has run since stoppin' for water

So, option B makes sense here
