Answer: Jill: 2mph and jack: 2 2/5 I had this in my test lol and tell me if it was right for you all
Answer:
There are many.
Step-by-step explanation:
When you say proportional, you are looking for a ratio that is equivalent to the ratio given. In your case, there are many so you might need to be more specific. But still, we can help you figure it out.
An easy way to do this would be to scale it down to its simplest form and then move upwards. To find proportional ratios, just multiply denominator and the denominator with the same factor.

That is your ratio in its simplest form. Now we can scale up, I'll show you how to do one completely:

That's the same ratio scaled up by a factor of 2.
---------------------------------------------------------------------------------------

That's the ratio given
---------------------------------------------------------------------------------------

Scaled up by a factor of 4
---------------------------------------------------------------------------------------

Scaled up by a factor of 5.
The list goes on and on.

Answer:
There are infinite solutions because there is always another number between any two numbers.
Step-by-step explanation:
Pick any number (including decimal) add an extra decimal after the smallest one and then you have a number between them. E.g.
1.234 and 2.987
1.2341, 1.2342, 1.2343, ... are all between them
