Answer:
(A)d=20h
Step-by-step explanation:
If Kia rides her bike at 20 miles per hour.
20 miles per hour is referred to as the Kia's Speed.
Now we know that:
Given:
- Number of hours traveled=h
- Distance traveled=d
- Speed = 20 mph
Substituting these three into the formula above, we have:
Cross multiply
d=20h
<u>The correct option is A.</u>
Using it's formula, the average rates of change are given as follows:
a) 30 meters per second.
b) -10 meters per second.
<h3>What is the average rate of change of a function?</h3>The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u> Hence, over an interval [a,b], the rate is given by the following equation:
For item a, taking the data from the table, we have that:
- f(0) = 0.
- f(4.6) = 138.
Hence the rate is given as follows:
r = (138 - 0)/(4.6 - 0) = 30 meters per second.
For item b, taking the data from the table, we have that:
- f(9.2) = 23.
- f(11.5) = 0.
Hence the rate is given as follows:
r = (0 - 23)/(11.5 - 9.2) = -10 meters per second.
