The Pythagoras' theorem and the uniform motion allows to find the answer for the rate of change of distance is
v = 32.3 m / s
The distance is the length of the segment that a white house wing with the helicopter, this can be found using the Pythagoras' theorem
R = 
Where R is the distance, x is the horizontal distance where the helicopter flies and y is the vertical distance that corresponds to the flight height
y = 500 m
Since the helicopter flies at constant speed, we can use the uniform motion relation
= 
x = t
Where is the speed of the helicopter and t is the time
We substitute
r = 
Kinematics defines velocity as the change of position in the unit of time
This expression is the change in distance as a function of time for a given speed. In the exercise, this speed is requested for a time of one minute, for the helicopter speed of
v = 2km/min (
) ( 
) = 33.33 m / s
Let's calculate
v = 
v = 32.3 m / s
In conclusion using the Pythagoras' theorem and the uniform motion we can find the answer for the rate of change in distance is
v = 32.3 m / s

The probability is analyzed with the help of statistics. The probability of the person buying cereal once a month through the Venn diagram is given as, 53/64. Thus, option C is correct.
<h3>What is the Venn diagram?</h3>
A Venn diagram is the illustration of the information or the data that are in relation to other data and are represented in the form of circles.
The Venn diagram shows the total number of people who eat breakfast (A) every day, and another set shows people who buy cereals (B).
n (A) = 11 + 53 = 64
n (B) = 53 + 4 = 57
n (AB) = 53
Probability of buying cereals for the person eating breakfast every day:
= P (B/A) = P(AB) / P(A) = n(AB )/ n(A) = 53/64
Therefore, option C. 53/64 is the probability.

Epilepsy is a central nervous system (neurological) disorder in which brain activity becomes abnormal, causing seizures or periods of unusual behavior, sensations and sometimes loss of awareness.
Anyone can develop epilepsy. Epilepsy affects both males and females of all races, ethnic backgrounds and ages.
