Question

Туристы прошли на север 200 метров. Затем они прошли 300 метров по азимуту 90 градусов ,после чего повернули на юг и прошли еще 400 метров. в каком направлении находится начало маршрута

Answer 1

Шли на север 200м, потом на восток 300м, потом на юг 400м.
Начало маршрута находиться на северо-западе.

(Если они пойдут на 200км севернее и после 300км западнее, вернуться в исходную точку :) )

Answer 2

Given Information:

- The tourists walked north for 200 meters. - They then walked 300 meters at an azimuth of 90 degrees. - After that, they turned south and walked another 400 meters.

Analysis:

To determine the direction of the starting point, we need to consider the movements of the tourists. Let's break down their movements step by step:

1. They walked north for 200 meters. 2. They then walked 300 meters at an azimuth of 90 degrees, which means they walked east. 3. Finally, they turned south and walked 400 meters.

Solution:

To find the direction of the starting point, we need to consider the net displacement of the tourists. We can add the northward and southward displacements and the eastward displacement to find the total displacement.

- Northward displacement: 200 meters - Southward displacement: 400 meters - Eastward displacement: 300 meters

To find the direction, we can use trigonometry. The angle can be calculated using the formula:

Angle = arctan(Eastward displacement / Net displacement)

Net displacement = Northward displacement - Southward displacement

Substituting the values:

Net displacement = 200 meters - 400 meters = -200 meters

Angle = arctan(300 meters / -200 meters)

Using a calculator, we find that the angle is approximately -56.31 degrees.

Since the angle is negative, it means the starting point is in the southwest direction.

Answer:

The starting point of the route is in the southwest direction.

Note: The search results did not provide specific information about the starting point, but the calculations based on the given information indicate that the starting point is in the southwest direction.
