A passenger train travels at a speed of 72 km/h. A man on the passenger train observes a

seconds, write a C++ function to find the length of the goods train

Answer 1

#include <iostream>
using namespace std;
int main(){
    int relative_speed = 72 - 54;
    float distance;
    cout<<"Enter number of seconds taken to pass the train: ";
    int x; cin>>x;
    cout<<"Length of the good train: "<<(float) relative_speed*1000/3600 * x<<" meters.\n";
    return 0;
}
