Answer:
135 minutes
Explanation:
36 cupcakes in 45 minutes can be written as
, so to find how long 108 will take, you can find it by equating these two fractions:
=
Simplify by cross division:
divide 45 and 108 by 3 to simplify into this:
=
x = 15
The rate is 3, so 45 • 3 = 135 minutes.
Another way of looking at it is this:
108 ÷ 36 = 3 this is the rate that you need to multiply the amount of time that it takes to make the cupcakes, so:
45 • 3 = 135 minutes.

Answer:
4 minutes.
Step-by-step explanation:
There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.
In his journey, she walks for 15 minutes and a train journey for about 53 minutes.
Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.
Therefore, the average waiting time, in minutes, at each of the three train stations will be 
minutes. (Answer)
Radius of cone is decreasing at the rate of 
inches
What is rate of change?
Suppose there is a function and there are two quantities. If one quantity of a function changes, the rate at which other quantity of the function changes is called rate of change of a function.
Here rate of change of radius of cone has been calculated
Radius of cone = 18 inches
Height of cone = 11 inches
Volume of cone (V) = 
Radius of cone is decreasing at the rate of inches
