ASA Electronics E6-B manual The rate arrow points to your ground speed, 120 knots, Speed, Time

In the final and most common type of time-speed- distance problem, the time and distance are known, and you need to solve for unknown speed. The rate arrow represents the answer. You will have flown between two known ground reference points 26 NM apart and checked the time between them to be: 13 (thirteen minutes, that is, not thirteen hours).

1.Set thirteen minutes on the middle scale op- posite to 26 on the outer scale. See Figure 5.

2.The rate arrow points to your ground speed, 120 knots.
