What are the computed true heading and groundspeed for a given cross-country flight?

In determining the computed true heading and groundspeed for a cross-country flight, the true heading reflects the direction the aircraft must fly over the ground to reach its destination, accounting for factors such as wind. The groundspeed indicates how fast the aircraft is progressing over the ground as opposed to its airspeed.

The choice indicating a true heading of 185 degrees and groundspeed of 106 knots is based on a scenario where the wind has been factored into the calculation of the aircraft's necessary directional flight and speed. This means that the wind effect was properly calculated to ensure a direct route to the destination, leading to that specific heading of 185 degrees. Additionally, a groundspeed of 106 knots indicates that the aircraft is experiencing a favorable wind or possibly a very light headwind, which results in an efficient flight speed, helping to estimate the time required to reach the destination more accurately.

In contrast, the other options could reflect deviations in either heading or groundspeed, which may not properly account for wind effect, or may suggest incorrect calculations based on the flown path and environmental conditions experienced. Each of those alternatives must take into consideration how the aircraft is actually navigating through the air with respect to the ground it is covering.
