Answer:
45 minutes have passed
Step-by-step explanation:
1 degree = 1 minute
To solve this problem, all you have to do is set up a proportion, letting x represent Kenneth's average speed per hour.
184.25/3.35 = x/1
Now, we use cross products, or the multiplication of the numerator of one fraction times the denominator of another fraction, and setting them equal to one another.
3.35x=184.25
Finally, we divide both sides by 3.35, because it's the coefficient of x, and we are trying to get the variable x alone.
x=55
Therefore, Kenneth's average speed was 55 miles per hour.

Melinda sold 8 packages of coffee and 6 packages of pastries
Step-by-step explanation:
The parameters given are;
Number of Packages of coffee = x
Number of Packages of pastries = y
Price of each package of coffee = $6
Price of each package of coffee = $4
Number of packages of packages of coffee sold = 2 more than packages of packages pastries sold
x = 2 + y
y = x - 2................(1)
Sum of money made in the fundraiser = $72
∴ x × $6 + y × $4 = $72
y = ($72 - x × $6)/$4 = 18 - 3/2·x
y = 18 - 3/2·x.........(2)
The solution is
x - 2 = 18 - 3/2·x
x + 3/2 = 18 + 2 = 20
5/2·x = 20
x = 2/5×20 = 8
y = x - 2 = 8 - 2 = 6
