Question

If I walk 21 miles at a steady rate of 3 miles per hour can my relationship be represented with a slope of -3

Answer 1

Answer:

The slope of given relationship is 7 and it is not - 3  

Step-by-step explanation:

Given as :

The distance cover while walking = d = 21 miles

The speed rate of walking = s = 3 miles per hour

Let The time taken to cover 21 miles = t hours

Now, According to question

∵ Distance = Speed × Time

So, Time = $\dfrac{\textrm Distance}{\textrm Speed}$

Or, t = $\dfrac{d}{s}$

Or, t = $\dfrac{\textrm 21 miles}{\textrm 3 miles per hour}$

∴  t = 7 hours

So,  The time taken to cover 21 miles = t = 7 hours

i.e slope of the given relationship = 7

Hence, The slope of given relationship is 7 and it is not - 3  . Answer
