Answer:

Step-by-step explanation:
we know that
She rides for 11.2 kilometers at a speed of 7 kilometers per hour
Using proportion
Find how many hours does she ride

10[(6 + 4) / 2]
10[10/2]
10 * 5
50 <==
Answer:
8
Step-by-step explanation:
f (x) = 7 (x-1) +8
For f(1) we plug 1 into x.
f(1) = 7 (1-1) +8
Simplify
f(1) = 8
Let's begin by listing out the information given to us:
We start out by observing that Triangles MKR & ACD are similar or proportional

We will solve for the missing side by using the similar triangle theorem. This is shown below:~
