Two trains leave a station at the same time on straight sections of track which form an angle of 67° with each other. The first train, a freight train, travels at 65 mph and the second, a bullet passenger train, at 94 mph. How far apart are the trains, correct to the nearest 0.1 mile, after two hours?

Concept explainers

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.

Question

Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
