Question

The distance a vehicle travels can be calculated as follows: Distance = Speed * Time For example, if a train travels 40 miles-per-hour for three hours, the distance traveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. Both values are assumed to be integers. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph for a three-hour time period, it should display a report similar to the one that follows: Hours Distance Traveled --------------------------- 1 40 2 80 3 120 Do not accept a negative number for speed and do not accept any value less than 1 for time traveled.

Answer 1

// here is code in C++.

// include headers

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{ // variable

double speed,hour;

cout<<"enter the speed of vehicle:";

// read speed

cin>>speed;

// check for the negative speed

while(speed<0)

{ // if speed is negative then again take input

cout<<"Speed can't be negative!!"<<endl;

cout<<"Enter the Speed again:";

cin>>speed;

}

//ask for hours

cout<<"enter hours traveled:";

//read hours

cin>>hour;

// check hours<1 or not

while(hour<1)

{

cout<<"hour can't be less than 1!!"<<endl;

cout<<"Enter the Hours again:";

cin>>hour;

}

// print the distance after each hour

cout<<"Hours \t Distance Traveled "<<endl;

cout<<"---------------------------"<<endl;

for(int h=1;h<=hour;h++)

{

cout<<h<<"\t"<<speed*h<<endl;

}

return 0;

}

Step-by-step explanation:

Read the speed of the vehicle and assign it to variable "speed".Then read the hours traveled and assign to "hour".After this print the each hour and distance traveled by multiplying speed with h .

Output:

enter the speed of vehicle:-10

Speed can't be negative!!

Enter the Speed again:40

enter hours traveled:.4

hour can't be less than 1!!

Enter the Hours again:3

Hours Distance Traveled

---------------------------

1 40

2 80

3 120
