Answer: <u>To establish a point from which to measure a future distance, or if movement has occurred.</u>
Explanation:
A reference point is a point with respect to which one comes to know whether any movement has occurred or not. A still point is required. When the object changes distance from that point, it means that object has moved. The distance can be calculated from one point to another.
Therefore, A reference point is used to establish a point from which future distance or if movement has occurred is detected.

Answer:
The correct answer is no.
Explanation:
The temperature of a person changes depending on their age, the physical activity they are doing and until the time of day.
There is an established average temperature that is 98.6 ° F (37 ° C) as a healthy temperature.
If the temperature exceeds 100.4 ° F (38 ° C) it means that you may be ill or have an infection.
The difference in temperature by age is very minimal, but it is still a difference. Let's see:
- Babies and children: from 97.9 ° F (36.6 ° C) to 99 ° F (37.2 ° C).
- Adults: from 97 ° F (36.1 ° C) to 99 ° F (37.2 ° C).
- Adults over age 65: 98.6 ° F (36.2 ° C).
It would be: Speed = Distance / Time
