Answer:
<u><em>Katie runs fastest </em></u>
Step-by-step explanation:
For us to know the person who runs fastest, we need to calculate their speed in feet per seconds (ft/s)
For Tony; his speed is 12ft/s
For Katie;
Katie runs 450 feet in 30seconds;
450 feet = 30 secs
x = 1 sec
Cross multiply
30x = 450
x = 450/30
x = 15ft
Hence Katie runs 15ft/s
For Frank;
Frank ran 1 mile per 577secs
1 mile = 5280feeet
This mean that he ran 5280feet in 577 secs
5280feet = 577secs
y = 1 secs
cross multiply;
577y = 5280
y = 5280/577
y = 9.15ft/s
Hence Frank ran 9.15ft/s
For Adam;'
If Adam ran 880 ft in 1 minutes, this means he ran 880ft in 60secs
880 ft = 60secs
z = 1sec
Cross multiply
60z = 880
z = 880/60
z = 14.67ft/s
Hence Adam ran 14.67ft/s
<em>From the value of their speed, we can see that </em><u><em>Katie runs fastest </em></u><em>with a speed of 15ft/s</em>
Answer:
just substitute 1, 2, 3, 4, and so on into the function and then you'll get your answer

Answer:
We can test for proportionality on a graph by looking for various properties.
- A proportional graph will always go through the origin (0,0)
- A proportional graph will be a straight line.
- If you list points (ordered pairs) from a graph, you can create ratios and see if they are constant (equal).
Step-by-step explanation: Check for these things when looking at the graph, and write down what the graphs lack.
