Answer:
Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.
Step-by-step explanation:
Given:
Steven swam 200 m in 25.7 seconds while Michelle finished in 28 seconds.
So, speed of Steven is,
Speed of Michelle is,
Now, to find how much faster did Steven swim than Michelle, we need to get the difference between their speeds.
Speed of Steven - Speed of Michelle
So, Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.
This is how you would solve the question.

Answer:
Q ≈ 0.0314148930589 radians ≈ 1.79994078613°
Step-by-step explanation:
There is no algebraic solution for the set of equations with mixed polynomial and trig functions:
x·sin(Q/2) = 5
1/2x^2(Q -sin(Q)) = π/12
__
However, we can use the first equation to substitute for x in the second equation. This gives ...
This can be simplified using the half-angle identity and recast as a function of Q:
This function will have a zero at the desired value of Q. It can be solved iteratively. A graph shows an approximate value of Q is 0.314 (radians). The value can be refined by Newton's method iteration to give the angle to full calculator precision:
Q ≈ 0.0314148930589 radians ≈ 1.79994078613°
__
The corresponding value of x is about 318.333447755. In short, this is a very narrow sector/segment in a relatively large circle.
