Do you know how many friends he has then you can answer the question
How would we do that here
Answer: It flies 108 miles in 3 hours.
Step-by-step explanation:
576/16 = 36
It flies 36 miles per hour
36 * 3 = 108
Remember that the general decay equation is:

where

is the amount after a time


is the initial amount

is the the decay percent in decimal form
The first ting we are going to do is find

by dividing our <span>decay rate of 25% by 100%: </span>

.
We also know from our problem that

. Lets replace

and

in our formula:


We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that
this situation represents exponential decay.
Now, to find the initial amount, we are going to solve our equation for

:


Notice that

will depend on the number of ours
