Answer:
The constant of proportionality k = 11.5.
The equation will be: 
Step-by-step explanation:
If x represents number of hours than y represents miles
We are given:
x y
4 46
5 57.5
6 69
The constant of proportionality can be found using formula: 
Putting values and finding k
x y k (
)
4 46 11.5
5 57.5 11.5
6 69 11.5
So, the constant of proportionality k = 11.5
Now, The equation will be:

So, the equation will be: 
Answer:
in fraction form: -1/36, 1/216, -1/1296
in decimal form: -.03, .005, -.0008
Step-by-step explanation:
Each term is the previous term divided by -6:
-36 ÷ -6= 6
6 ÷ -6= -1
and so on...
I day = 24 hours
90/24 = ?
90/24 = 3 times
3 days and 75% of a day.
Now we need to find 75% of 25.
18.75 hours
Answer: 3 days and 18.75 hours
