Answer:
A = 0.65
B = 3.304
C = 6.07
Step-by-step explanation:
You have to subtract to the final result the initial one and divide it for the number of segments. Then, for every segment you add the number you found, for example:
Value of a segment:
![\frac{1 - 0.5}{10} = 0.05](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20-%200.5%7D%7B10%7D%20%20%3D%200.05)
Value of A:
![0.5 + 3 \times 0.05 = 0.65](https://tex.z-dn.net/?f=0.5%20%2B%203%20%5Ctimes%200.05%20%3D%200.65)
56.25 minutes
Explanation: to find how long it takes to run one mile, divide 50 minutes by 8 miles.
50/8 = 6.25
Then you can multiply 6.25 by 9 to find the answer.
9 x 6.25 = 56.25 minutes
