Calculate Distance Between -1.5 And 11.9 Made Easy

Quick Links :

Calculating the distance between two numbers is a basic mathematical operation that can be done in a few simple steps. In this article, we will guide you through the process of calculating the distance between -1.5 and 11.9.

What is Distance Between Two Numbers?

The distance between two numbers is the absolute difference between them. It is a measure of how far apart the two numbers are on the number line. The distance between two numbers can be calculated using the formula:

Distance = |a - b|

Where a and b are the two numbers.

How to Calculate Distance Between -1.5 and 11.9

To calculate the distance between -1.5 and 11.9, we can use the formula:

Distance = |11.9 - (-1.5)|

First, we subtract -1.5 from 11.9:

11.9 - (-1.5) = 11.9 + 1.5 = 13.4

Then, we take the absolute value of the result:

|13.4| = 13.4

So, the distance between -1.5 and 11.9 is 13.4.

Why is the Distance Between Two Numbers Important?

The distance between two numbers is an important concept in mathematics and has many real-world applications. It can be used to:

• Measure the difference between two quantities
• Calculate the distance between two points on a graph
• Determine the length of a line segment
• Solve problems involving relative motion

In real-world scenarios, the distance between two numbers can be used to calculate the distance between two cities, the difference between two temperatures, or the length of a bridge.

Calculating Distance Between Two Numbers with Negative Values

When calculating the distance between two numbers with negative values, it's essential to remember that the negative sign represents the opposite direction on the number line. For example, -1.5 is 1.5 units to the left of 0 on the number line.

To calculate the distance between two numbers with negative values, we can use the same formula:

Distance = |a - b|

However, we need to be careful when subtracting negative numbers. When we subtract a negative number, we are essentially adding a positive number.

For example:

Distance = |-1.5 - (-3.2)| = |-1.5 + 3.2| = |1.7| = 1.7

So, the distance between -1.5 and -3.2 is 1.7.

Tips and Tricks for Calculating Distance Between Two Numbers

Here are some tips and tricks for calculating the distance between two numbers:

• Always use the absolute value formula: Distance = |a - b|
• Be careful when subtracting negative numbers. When we subtract a negative number, we are essentially adding a positive number.
• Use a number line to visualize the distance between two numbers.
• Practice, practice, practice! The more you practice calculating the distance between two numbers, the more comfortable you'll become with the concept.

Real-World Applications of Calculating Distance Between Two Numbers

Calculating the distance between two numbers has many real-world applications, including:

• Physics: to calculate the distance between two objects in motion
• Engineering: to calculate the length of a bridge or a tunnel
• Computer Science: to calculate the distance between two points on a graph
• Navigation: to calculate the distance between two cities or landmarks

In conclusion, calculating the distance between -1.5 and 11.9 is a simple mathematical operation that can be done using the formula: Distance = |a - b|. By understanding the concept of distance between two numbers, we can solve a wide range of problems in mathematics and real-world applications.
