Answer:
Step-by-step explanation:
<u>Constant Speed Motion
</u>
When the object travels the same distances in the same period of time, the speed is constant and is can be calculated as
where x is the distance and t is the time
There are two canoes traveling at speeds v1 and v2. One of them has twice the speed as the other. Let's say
When t hours have passed, the canoes have traveled x1 and x2 respectively.
Since
Then
The distance between them is
That distance is known and equals 11.25 miles, thus
Solving for v1 and using t=4.5 hours
Answer: It is proportional because 195/3 equals 65 and 325/5 equals 65 as well, so it is proportional.

Rotation of 180° about the origin
Answer:
X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
