Answer:
X has travelled 4 times as far as Y
X is moving 2 times as fast as Y
Explanation:
Because x=1/2at²(get rid of the first portion of x=vt+1/2at² because initial v is 0 which multiplies to 0). If the acceleration is set to for example 10 (keep this constant for both X and Y) and we use t=1 and t=2 for time (as the time travelled of X is twice that of Y). Plugging this into the equation, at t=1, x=4. At t=2, x=20. 20 is four times greater than 5, so X has travelled 4 times as far as Y.
To find the difference in speed between the two objects, use the equation 
. Since the initial velocity is 0, that part can just be removed from the equation. With v=at, it is easy to see that if the time plugged in is twice for one than the other (and the acceleration is the same for both), the final result will be twice of the other as well. For example: If the acceleration is 10 again for both, then v=10t. If t is 1, the velocity is 10. If t is 2, the velocity is 20.

The true statement about the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Plans and the impact to Plans C and F are:
- "Consumers eligible for Medicare Part A on or after January 1, 2020,will not be able to purchase Medicare Supplement Insurance Plans C or F."
- "Consumers eligible for Medicare Part A before January 1 2020 can enroll in Plan C or F even after 2020 and can keep their plans as long as they choose."
<h3>What is
MACRA?</h3>
MACRA is an abbreviation for Medicare Access and CHIP Reauthorization Act of 2015 and it can be defined as a bipartisan United States statute (legislation) that was signed into law on the 16th of April, 2015, so as to change how the federal government pay physicians in the United States of America.
Based on the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Plans, the impact to Plans C and F include the following:
- "Consumers eligible for Medicare Part A on or after January 1, 2020,will not be able to purchase Medicare Supplement Insurance Plans C or F."
- "Consumers eligible for Medicare Part A before January 1 2020 can enroll in Plan C or F even after 2020 and can keep their plans as long as they choose."
