5. The Distance ProblemA Car Travels At A Constant Speed Of 60 Miles Per Hour. If The Car Has Traveled 240 Miles, How Many Hours Has It Been Driving?
Introduction
In this article, we will explore the concept of distance, speed, and time, and how to use these variables to solve problems. Specifically, we will focus on the distance problem, where we are given the distance traveled and the speed at which it was traveled, and we need to find the time it took to travel that distance. We will use a real-world example to illustrate this concept.
What is the Distance Problem?
The distance problem is a fundamental concept in mathematics that involves finding the time it takes to travel a certain distance at a constant speed. It is a classic problem in physics and engineering, and it has many practical applications in fields such as transportation, logistics, and navigation.
The Formula: Distance = Speed x Time
The distance problem can be solved using the formula:
Distance = Speed x Time
This formula states that the distance traveled is equal to the speed at which it was traveled multiplied by the time it took to travel that distance. We can rearrange this formula to solve for time:
Time = Distance / Speed
Example: A Car Travels 240 Miles at 60 Miles Per Hour
Let's use a real-world example to illustrate how to solve the distance problem. Suppose a car travels at a constant speed of 60 miles per hour and has traveled 240 miles. How many hours has it been driving?
We can use the formula Time = Distance / Speed to solve this problem. Plugging in the values, we get:
Time = 240 miles / 60 miles per hour
Time = 4 hours
Therefore, the car has been driving for 4 hours.
Why is the Distance Problem Important?
The distance problem is an important concept in mathematics because it has many practical applications in fields such as transportation, logistics, and navigation. For example, if you are planning a road trip, you need to know how long it will take to travel a certain distance at a certain speed. This information can help you plan your trip, including the time you need to leave, the amount of fuel you need to bring, and the number of rest stops you need to make.
