Jason walked 600 m due east from point P to point Q and then walked 800 m due north from point Q to point R. If Jason walked straight from point P to point R, find the difference between the two distance from point P to point R.
Jason berjalan 600 m ke arah timur dari titik P ke titik Q dan seterusnya berjalan 800 m ke arah utara dari titik Q ke titik R. Jika Jason berjalan terus dari titik P ke titik R, cari beza antara kedua-kedua jarak dari titik P ke titik R.

Distance word problems are a common type of algebra word problems. They involve a scenario in which you need to figure out how fast, how far, or how long one or more objects have traveled. These are often called train problems because one of the most famous types of distance problems involves finding out when two trains heading toward each other cross paths.
In this lesson, you'll learn how to solve train problems and a few other common types of distance problems. But first, let's look at some basic principles that apply to any distance problem.
The basics of distance problems
There are three basic aspects to movement and travel: distance, rate, and time. To understand the difference among these, think about the last time you drove somewhere.
The distance is how far you traveled. The rate is how fast you traveled. The time is how long the trip took.
The relationship among these things can be described by this formula:
distance = rate x time
d = rt
Answer:
According to Bohr Atomic model, a small positively charged nucleus is surrounded by revolving negatively charged electrons in fixed orbits. He concluded that electron will have more energy if it is located away from the nucleus whereas the electrons will have less energy if it located near the nucleus.
