Alright, this is kind of calculus and kind of physics. You don't have to give me the actual answer, I just would like to know how to get started.
A marching army column is 1km long. A courier is sent running from the column's rear to the front with a message, and is immediately sent back to the rear with a reply. During the time the courier is running, the column marches 10km. How far does the courier run?

Best ResponseYou've already chosen the best response.0hi, knowing that the marching army has 1000 meter in distance, you need to calculate the courier and the marching armies velocity or speed going to 10,000 meter,(try 100 meter per minute)..once you know their speed, when the courier is going back, his velocity and the armies velocity added up,then here you can get the distance plus the 10,000 meters.......
