Question

Write a program that calculates the total duration of
the trip and also the direction in which the customer has travelled.​

Answer 1

Answer:

// C++ Program to calculate speed

// distance and time

#include<iostream>

using namespace std;

// Function to calculate speed

double cal_speed(double dist, double time)

{

cout << "\n Distance(km) : " << dist ;

cout << "\n Time(hr) : " << time ;

return dist / time;

}

// Function to calculate distance traveled

double cal_dis(double speed, double time)

{

cout << "\n Time(hr) : " << time ;

cout << "\n Speed(km / hr) : " << speed ;

return speed * time;

}

// Function to calculate time taken

double cal_time(double dist, double speed)

{

cout << "\n Distance(km) : "<< dist ;

cout << "\n Speed(km / hr) : " << speed ;

return speed * dist ;

}

// Driver function

int main()

{

// Calling function cal_speed()

cout << "\n The calculated Speed(km / hr) is : "

<< cal_speed(45.9, 2.0 ) << endl ;

// Calling function cal_dis()

cout << "\n The calculated Distance(km) : "

<< cal_dis(62.9, 2.5) << endl ;

// Calling function cal_time()

cout << "\n The calculated Time(hr) : "

<< cal_time(48.0, 4.5) << endl ;

return 0;
