Answer:
Do you want to be extremely boring?
Since the value is 2 at both 0 and 1, why not make it so the value is 2 everywhere else?
 is a valid solution.
 is a valid solution.
Want something more fun? Why not a parabola?  .

At this point you have three parameters to play with, and from the fact that  we can already fix one of them, in particular
 we can already fix one of them, in particular  . At this point I would recommend picking an easy value for one of the two, let's say
. At this point I would recommend picking an easy value for one of the two, let's say  (or even
 (or even  , it will just flip everything upside down) and find out b accordingly:
, it will just flip everything upside down) and find out b accordingly:
Our function becomes 
 
 
Notice that it works even by switching sign in the first two terms: 
Want something even more creative? Try playing with a cosine tweaking it's amplitude and frequency so that it's period goes to 1 and it's amplitude gets to 2: 
Since cosine is bound between -1 and 1, in order to reach the maximum at 2 we need  , and at that point the first condition is guaranteed; using the second to find k we get
, and at that point the first condition is guaranteed; using the second to find k we get 

Or how about a sine wave that oscillates around 2? with a similar reasoning you get 

Sky is the limit.
 
        
             
        
        
        
The first part of the question is not needed 
we only need to know M1 and M2
(y2-y1)^2+(x2-x1)^2=(your answer)^2
(5-16)^2+(-3-2)^2=(your answer)^2
(-11)^2+(-5)^2=(your answer)^2
121+25=(your answer)^2
146=(your answer)^2
√146=12.0830459735945721
nearest tenth=12.1
        
             
        
        
        
You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.
I wish this helps. :)
