10 km ÷ 2.5 hours = 4 km/h — This is Sara's record
7.5 km ÷ 2 hours = 3.75 km/h — This is Katerina's record
9.5 km ÷ 2.25 hours = 4.2 km/h — This is Candice's record

Option D is the correct option.
Step-by-step explanation:
Given,
![\sf{f(x) = - 2x + 5}](https://tex.z-dn.net/?f=%20%5Csf%7Bf%28x%29%20%3D%20%20-%202x%20%2B%205%7D)
To find : f ( - 3 )
Let's find:
![\sf{f( - 3) = - 2 \times ( - 3) + 5}](https://tex.z-dn.net/?f=%20%5Csf%7Bf%28%20-%203%29%20%3D%20%20-%202%20%5Ctimes%20%20%28%20-%203%29%20%2B%205%7D)
Calculate the product
![\sf{ = 6 + 5}](https://tex.z-dn.net/?f=%20%5Csf%7B%20%3D%206%20%2B%205%7D)
Add the numbers
![\sf{ = 11}](https://tex.z-dn.net/?f=%20%5Csf%7B%20%3D%2011%7D)
Hope I helped!

Answer:
Yes. They're equivalent.
Step-by-step explanation:
1/8-10(3/4-3/8x)+5/8x
1/8-30/4+30/8x+5/8x
1/8-60/8+35/8x
-59/8+35/8x
factor out -1/8
-1/8(59-35x)
