:: Column of Troops :: A column of troops one km long is moving along a straight road at a uniform pace. A messenger is sent from the head of the column, delivers a message at the rear of the column and returns. He also moves at a uniform pace and arrives back at the head of the column when it has just covered its own length. How far did the messenger travelled? Answer: 1+sqrt(2) or 2.414 km (to 3 decimal places). |
