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 difference = miles rode on Tuesday - miles rode on Thursday.
6 5/6 - 5 5/6 = 1 mile
        
             
        
        
        
Use PEMDAS for this problem.
1 x 1000=   + 1000
3 x 10,000= 30,000
---------------------------
                 + 31000
                       9000
---------------------------
                 + 40000
                         800
--------------------------
                    + 40800
                              50
------------------------------
                       + 40850
                                  2

Answer:
-7/2 or -3.5
Step-by-step explanation:
Make the equation first
7x-1 = 5x-8
7 = -2x
-7/2 = x
