Here is another version of the circular Time Speed Distance computer. You can print this out on cardstock to use in the game.
TSD Circular computer
For those who have never used this:
You line up the arrow with your speed on the outer wheel, then you can read time (hours) on the inner wheel vs distance on the outer wheel.
EXAMPLE
line up the arrow (1) with 22(kts), this is also 44000yds/hr. In 1/2 hr you will travel 11 mi or 22000 yards. in 34 hrs you will travel approx. 750 mi.
If you line up the 6 on the inner wheel with your speed, you can read the time in minutes, as the wheel repeats. 6~60~600...
Line up the 6 (60) with 8 kts. In 22 minutes you will travel approx 2.9 mi (5900 yds). You will travel 14 mi in 105 minutes.
Enjoy,
Mike
