Word Problem with bearings, distance traveled

The video tutorial explains how to calculate the northward distance a plane travels using its bearing and distance traveled. It begins with an introduction to the problem, followed by a detailed explanation of how to convert bearing into a decimal. The instructor sets up the problem using a right triangle and identifies the necessary variables. The tutorial then demonstrates solving a trigonometric equation to find the northward distance, concluding with the final calculation and rounding the result to the nearest thousandth.

What is the initial bearing of the plane as it leaves the airport?

• N 17 degrees 30 minutes W

• E 17 degrees 30 minutes N

• S 17 degrees 30 minutes E

• N 30 degrees 17 minutes W

How is the bearing of N 17 degrees 30 minutes W converted into decimal degrees?

• 17.8 degrees

• 17.5 degrees

• 17.6 degrees

• 17.3 degrees

In the problem setup, what does the variable 'D' represent?

• The altitude of the plane
