Related rates change in distance between two boats?

In summary, the question asks for the rate of change of the distance between two boats that leave a dock at the same time, one going south at 30 km/h and the other going southwest at 40 km/h. The individual is unsure of how to approach this since it involves non-right triangles, but suggests creating two right triangles by drawing a line perpendicular to the path of the second boat and knowing the angle between the two paths.

Homework Statement


Two boats leave a dock at the same tie. One goes south at 30 km/h and the other goes southwest at 40 km/h. What is the rate of change of the distance between the 2 boats, 30 minutes after they leave?

I know how to do these questions when it's a right triangle...but since this has one boat going south, and one going southwest...I don't know how to do it.

I think you can make 2 right triangles by drawing a line from the position of first boat perpendicular to the path of the 2nd boat. Also, don't you know the angle between the paths of the two boats?

1. What is the concept of related rates change in distance between two boats?

The concept of related rates change in distance between two boats is a mathematical concept that deals with the change in distance between two moving objects. It involves finding the rate at which the distance between the two objects is changing with respect to time.

2. How is the related rates change in distance between two boats calculated?

The related rates change in distance between two boats is calculated using the distance formula, which is the square root of the sum of the squares of the differences between the corresponding coordinates of the two boats. This is then differentiated with respect to time to find the rate of change.

3. What are the key factors that affect the related rates change in distance between two boats?

The key factors that affect the related rates change in distance between two boats include the speeds and directions of the boats, the initial distance between them, and any external forces such as wind or currents.

4. Can related rates change in distance between two boats be negative?

Yes, related rates change in distance between two boats can be negative if the distance between the boats is decreasing. This can happen if the boats are moving towards each other or if one boat is moving faster than the other in the opposite direction.

5. How can related rates change in distance between two boats be applied in real-life situations?

Related rates change in distance between two boats can be applied in real-life situations such as calculating the speed of two boats when they are approaching each other, determining the time it takes for one boat to catch up to another, or calculating the rate at which the distance between two boats is changing due to external forces.
