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.
Answer:
60 sec.
Explanation:
The first person has to travel 200m at 2 m/s. It will take him 200/2=100 seconds to reach the gate. The second person is moving towards the gate at 2 + 3 meters per second so it will take her 200/5 = 40 seconds to reach the gate. Therefore, person #1 needs an extra 100-40 = 60 seconds.
The given statement is False. Baker, Schultz, and Halstead argue that the United States can reap significant strategic and economic benefits by investing in cleaner energy technologies and supporting international efforts to reduce carbon emissions.
Carbon emissions are the primary cause of global climate change. It is widely acknowledged that in order to avoid the worst effects of climate change, the world must urgently reduce emissions. However, how this responsibility is distributed among regions, countries, and individuals has long been a source of contention in international discussions.
This debate stems from the various ways emissions are compared, including annual emissions by country, emissions per person, historical contributions, and whether or not they account for traded goods and services. These metrics can tell a variety of stories.

Quantitative methods of control are tools or instruments used to facilitate and carry out control that uses numerical values for planning in decision making, some of these methods are:
It is the method of formal quantitative expression of the objectives that the administration of the company proposes to achieve in a period, its purpose is the appropriate allocation of the resources available to the entity.
The audit is a control method to improve the organization, management and administration of risks, providing a vision and recommendations based on the analysis and evaluation of data and processes.
Therefore, we can conclude that quantitative methods of control are instruments that have a measurable and controllable characteristic, among these methods are budgets and audits.
