This question is incomplete, the complete question is;
Katie Ledecky swims the length of a 50m Olympic size pool in 25 seconds and swims the return trip to the starting position in 26 seconds. What are her average velocities during:
a) The first half of the swim?
b) The second half of the swim?
Answer:
a) her average velocities during the first half = 2 m/s
b) her average velocities during the second half = 1.923 m/s
Step-by-step explanation:
Given that;
displacement = 50 m
time taken t = 25 secs
a)
average velocity = displacement / time taken = 50 / 25 = 2 m/s
Therefore her average velocities during the first half = 2 m/s
b)
In the second half;
displacement = 50 m
time taken t = 26 secs
average velocity = displacement / time taken = 50 / 26 = 1.923 m/s
Therefore her average velocities during the second half = 1.923 m/s

Answer:
15.8 meters
Step-by-step explanation:
We have the following information:
The length of the intercepted arc for the circle R = 103 * π meters
The arc length of circle S = 163 * π meters
We also know the radius of the circle R (10) but not that of the circle S (x).
We are told that circles R and S have a central angle that measures 60 °. Therefore, the radius of circle S to the radius of circle R is equal to the length of the intercepted arc S to the length of the arc R, thus:
Radius S / Radius R = Length S / Length R
I know all, except the radius of S, we organize for this value and we have:
Radius S = (Length S / Length R) * Radius R
Replacing:
Radius S = (163 * π / 103 * π) * 10
Radius S = 15,825 meters
So the radius of the circle S = 15.8 meters
Answer:
4/50 or 2/25
Step-by-step explanation:
Slope/rate of change is defined as the vertical distance over horizontal. then simplify.
