A section of highway has a free-flow speed of 55 mph and a capacity of 3300 veh/hr. In a given hour, 2100 vehicles were counted
alexira [117]

Answer:

Space mean speed = 44 mi/h

Explanation:

Using Greenshield's linear model

q = Uf ( D - D^{2}/Dj )

qcap = capacity flow that gives Dcap

Dcap = Dj/2

qcap = Uf. Dj/4

Where

U = space mean speed

Uf =  free flow speed

D = density

Dj = jam density

now,

Dj = 4 × 3300/55

    = 240v/h

q = Dj ( U - U^{2}/Uf)

2100 = 240 ( U - U^{2}/55)

Solve for U

U = 44m/h

blsea [12.9K]

Answer:

The solution code is written in Java.

  1. public class Movie {
  2.    private double  [][] seats = new double[5][5];
  3.    private double totalSales;
  4.    public Movie(){
  5.        for(int i= 0; i < this.seats.length; i++){
  6.            for(int j = 0; j < this.seats[i].length; j++){
  7.                this.seats[i][j] = 12;
  8.            }
  9.        }
  10.        this.totalSales = 0;
  11.    }
  12.    public boolean bookSeat(int i, int j)
  13.    {
  14.        if(this.seats[i][j] != 0){
  15.            this.totalSales += this.seats[i][j];
  16.            this.seats[i][j] = 0;
  17.            return true;
  18.        }else{
  19.            return false;
  20.        }
  21.    }
  22. }

Explanation:

The method, bookSeat(), as required by the question is presented from Line 16 - 26 as part of the public method in a class <em>Movie</em>.  This method take row,<em> i</em>, and column,<em> j</em>, as input.

By presuming the seats is an two-dimensional array with all its elements are  initialized 12 (Line 7 - 10). This means we presume the movie ticket price for all the seats are $12, for simplicity.

When the<em> bookSeat() </em>method is invoked, it will check if the current price of seats at row-i and column-i is 0. If not, the current price, will be added to the <em>totalSales </em>(Line 19)<em> </em>and then set the price to 0 (Line 20) and return <em>true</em> since the ticket is successfully sold (Line 21).  If it has already been sold, return <em>false</em> (Line 23).
