Can you solve the 12 dot puzzle? The challenge is to connect every dot with five straight lines. However, each line must connect to the last (think about a pen you cannot pick up from the paper). The twist to this is that the last line must end at the beginning of the first line.

There is a 50m long army platoon marching ahead. The last person in the platoon wants to give a letter to the first person leading the platoon. So while the platoon is marching he runs ahead, reaches the first person and hands over the letter to him and without stopping he runs and comes back to his original position. In the mean time the whole platoon has moved ahead by 50m.

The question is how much distance did the last person cover in that time. Assuming that he ran the whole distance with uniform speed.
