Answer : The Susana swam the fastest.
Step-by-step explanation :
Speed : It is defined as the distance traveled per unit time.
Formula used :

First we have to determine speed of the following persons.
<u>For Tawni :</u>
Distance = 50 m
Time = 40.8 s

The speed of Tawni is, 1.225 m/s
<u>For Pepita :</u>
Distance = 100 m
Time = 60.2 s

The speed of Pepita is, 1.661 m/s
<u>For Susana :</u>
Distance = 200 m
Time = 112.4 s

The speed of Susana is, 1.779 m/s
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
Answer:
Step any explanation:
t & 1/r
t = k/r
When t =6 and r = 5
k = tr
k = 6×5
k = 30
Constant of proportionality is equal 30
Answer:
Sin X=Cos Y
Step-by-step explanation:
Objective: Understand trigonometric relations such that
Cosine and Sine are similar to complementary angles that if X+Y are complementary angles,
Cos X= Sin Y and Cos Y= Sin X
2x 10 = 4x - 1
-2x - 10 = -1
-2x = 9
x = -9/2
y = 2(-9/2) -10
y = -9 - 10
y= -19
Answer: 40 centimeters is 15.748 inches.
Step-by-step explanation:
To start things off, a centimeter is equal to about 39.37 inches. If you want to know how to multiply a centimeter to get an inch, just multiply the quanity in centimeter by 0.39370078740157 or into smaller terms, 39.37. By doing so, you will get the answer, 15.748 inches by multiplying by centimeters.
