Given that the subway stations are 930 m apart, the train have to be accerelated for half the distance and then decerelated for the rest of the distance.
Recall that the distance travelled by an object with an initial velocity, u, for a period of time, t, at an accereration, a, is given by

But, we assume that the train accelerates from rest, thus

The maximum speed is attained at half the center of the distance between subway stations (i.e. at distance = 465 m).
Thus, maximum speed = distance / time = 465 / 23.12 = 20.11 m/s.
The angles are congruent and corresponding. You can find the missing angles by subtracting the existing ones from 180.
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
108x/56x Hope that helps.
