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 using python that asks the user for the speed of a vehicle in mph and the number of hours it has traveled. It should then use a while loop to display
the distance the vehicle has traveled for each hour of that time period.
Be sure to use input, format, and while loop correctly. Here's an example

Enter the speed of the vehicle in mph: 40
Enter the number of hours traveled: 3

Hours   Distance Traveled
-----------------------------------------------------------
1            40
2            80
3            120

Answer 1

Python Program:

def main():
   """
       Python program that calculates the distance a vehicle travelled
   """
  
   # Reading speed
   speed = int(input("\n Enter the speed of the vehicle in mph: "));
  
   # Reading time
   hours = int(input("\n\n Enter the number of hours travelled: "));
  
   # Variable for running for time
   hour = 1;
  
   print("\n\n %-10s %-10s \n" %("Hours", "Distance Travelled"));
   print("\n_________________________________________");
  
   # Iterating over while loop
   while hour <= hours:
      
       # Calculating speed using formula distance = speed * time
       distance = speed * hour;
      
       #Printing result
       print("\n %-10d %-10d " %(hour, distance));
      
       # Incrementing hours
       hour += 1;
      
      
   print("\n\n");
  
  
# Calling main function
main();
