Oct 13, 2025 by wbrum.org 56 views

Introduction

In this article, we will explore the relationship between distance, speed, and time. We will use a real-world scenario to demonstrate how these variables interact with each other. Andrew is planning to drive from his house to City A without stopping. We will calculate the time it takes for Andrew to complete his journey and then use this information to write an equation for the distance traveled.

Given Information

Distance from Andrew's house to City A: 200 miles
Speed at which Andrew plans to drive: 25 miles per hour

Calculating Time

To calculate the time it takes for Andrew to complete his journey, we can use the formula:

Time = Distance / Speed

Plugging in the given values, we get:

Time = 200 miles / 25 miles per hour

Time = 8 hours

Table of Values

Time (hours)	Distance (miles)
0	0
1	25
2	50
3	75
4	100
5	125
6	150
7	175
8	200

Writing an Equation for Distance

Now that we have calculated the time it takes for Andrew to complete his journey, we can write an equation for the distance traveled. We know that the distance traveled is equal to the speed multiplied by the time. Therefore, we can write the equation as:

D = 25t

where D is the distance traveled and t is the time in hours.

Interpreting the Equation

The equation D = 25t tells us that the distance traveled is directly proportional to the time. This means that if we double the time, the distance traveled will also double. Similarly, if we triple the time, the distance traveled will also triple.

Graphing the Equation

We can graph the equation D = 25t by plotting the points (0, 0), (1, 25), (2, 50), (3, 75), (4, 100), (5, 125), (6, 150), (7, 175), and (8, 200). The resulting graph will be a straight line with a slope of 25.

Conclusion

In this article, we have explored the relationship between distance, speed, and time. We have calculated the time it takes for Andrew to complete his journey and then used this information to write an equation for the distance traveled. The equation D = 25t tells us that the distance traveled is directly proportional to the time. This equation can be used to solve problems involving distance, speed, and time.

Real-World Applications

The equation D = 25t has many real-world applications. For example, it can be used to calculate the distance traveled by a car, a plane, or a train. It can also be used to calculate the time it takes to complete a journey, given the distance and speed.

Tips and Tricks

When solving problems involving distance, speed, and time, make sure to use the correct units. For example, if the speed is given in miles per hour, make sure to use hours as the unit of time.
When graphing the equation D = 25t, make sure to plot the points correctly. The resulting graph should be a straight line with a slope of 25.
When using the equation D = 25t to solve problems, make sure to check your units. For example, if the distance is given in miles, make sure to use miles as the unit of distance.
