Bearings & Direction Quiz

What is a bearing in navigation?

• A type of ship used for navigation

• A direction or angle measured in degrees from a reference direction, typically north

• A tool used to measure distances at sea

• A method of calculating speed in navigation

How do you express a bearing of 302° as a compass directional bearing?

• N58°W

• S58°E

• N32°E

• S32°W

What is the difference between true bearing and compass bearing?

• True bearing is measured clockwise from north, while compass bearing uses cardinal directions (N, S, E, W) to indicate direction.

• True bearing is measured counterclockwise from south, while compass bearing uses degrees to indicate direction.

• True bearing and compass bearing are the same; both use cardinal directions for measurement.

• True bearing is measured in radians, while compass bearing is measured in degrees.

What is the significance of bearings in navigation?

• Bearings are used to measure the speed of a vessel.

• Bearings help in determining the direction to travel from one point to another, essential for navigation.

• Bearings are only important for air navigation.

• Bearings indicate the distance to the nearest port.

If a ship sails at a bearing of S15°E, what is the true bearing?

• 150°

• 165°

• 180°

• 175°

What is the formula to convert compass bearings to true bearings?

• For bearings in the first quadrant (N), true bearing = angle; for S bearings, true bearing = 180° + angle.

• For bearings in the second quadrant (E), true bearing = 90° - angle; for W bearings, true bearing = 270° - angle.

• For bearings in the third quadrant (S), true bearing = angle; for N bearings, true bearing = 360° - angle.

• For bearings in the fourth quadrant (W), true bearing = 180° - angle; for E bearings, true bearing = 90° + angle.

What is the true bearing for N76°W?

• 270°

• 284°

• 300°

• 250°

How do you find the bearing of a point given its coordinates?

• Use the arctangent function to calculate the angle from the north direction based on the coordinates.

• Calculate the distance from the origin using the Pythagorean theorem.

• Use the sine function to determine the angle from the east direction.

• Find the midpoint of the coordinates and measure the angle from there.

What is the bearing of 90° in compass terms?

• N (North)

• W (West)

• S (South)

• E (East)

If a sailboat leaves the dock heading N30°E and travels 100 kilometers, how far east of the dock is the sailboat?

• 30 km

• 50 km

• 70 km

• 90 km
