To calculate time between two VORs, what formula should be used?

The correct formula to calculate the time taken to travel between two VORs is derived from the basic relationship between distance, speed, and time. The formula Time = Distance / Ground Speed shows how long it will take to cover a certain distance at a specified ground speed.

In aviation, when pilots are navigating from one VOR (VHF Omni-directional Range) to another, they need to know the distance between the two VOR stations and the ground speed at which their aircraft is traveling. By dividing the distance by the ground speed, they can accurately determine the time it will take to reach the next VOR. This calculation is crucial for effective flight planning and maintaining intended schedules.

The other options do not accurately reflect the relationship needed for this context. Option A suggests a multiplication that gives an incorrect calculation for time, while Option B incorrectly implies that the two factors should be multiplied rather than dividing the distance by the ground speed. Option D reverses the necessary calculation, leading to a misinterpretation of how time is derived from distance and speed. Thus, using the correct formula ensures that pilots can make accurate estimates of their flight times between navigational points.
