No Time
Puzzler time.
This one is sort of automotive in nature. Here we go.
In qualifying for a Trophy Off Road Race, potential drivers and their teammates were told that they had to traverse a course in as close a time as their partners without the use of time pieces like clocks, watches, or anything like that.
For example, the first person of the two person team would drive the course through the woods, over bridges, through streams and then return to the starting point and give his vehicle to his partner, who would then drive the same course and try to finish it as close to the time of his partner. So if the first partner finished in four minutes and 25 seconds, the other guy would try to duplicate that time.
But how could he do that without the use of any kind of clock or timepiece?
How could he possibly finish in the same time? That's the question. So the guys that won the race figured out a way to finish in the same time.
How did they do it?
Good luck.
