Answer:
7 min = 2mi
14min = 4mi
21min = 6mi
28min = 8mi
35min = 10mi
Step-by-step explanation:
Let x be the time, and y be the distance
In this case:
x = 2/7y
You can use this formula to answer all of the sections.
Hope this helped.
Solution :
a).
1. The domain of C(x)

Range of c(x) is 
Since the negative value do not make any sense.
2. C(x) = Ax + b
Intercept here denotes the fixed cost (that is when x = 0)
The slope indicates the marginal cost (that is increase in cost per unit of quantity)
3. Revenue is maximum marginal revenue = 0
(that is when at the top of the parabola)
4. Profit = R(x) -C(x)
5. Range of P(x) is important so that we have the idea in mind about the maximum loss and the maximum profit for a particular quantity.
