The average distance from Earth to the Moon is \(384,000 \mathrm{km}\). How many days would it take you, traveling at \(800 \mathrm{km} / \mathrm{h}-\) the typical speed of jet aircraft-to reach the Moon?

Understanding the relationship between distance and speed is key to solving travel time problems. When you know both the distance to your destination and your traveling speed, you can calculate how long it will take to get there. The basic formula to use is: \( t = \frac{d}{s} \), where \( t \) represents time, \( d \) represents distance, and \( s \) represents speed.
For example, in the problem of traveling from Earth to the Moon, the average distance is \( 384,000 \text{ km} \) and the typical speed of a jet aircraft is \( 800 \text{ km/h} \). By plugging these values into the formula, you get: \( t = \frac{384,000 \text{ km}}{800 \text{ km/h}} = 480 \text{ hours} \). This tells you that it would take 480 hours to travel this distance at that speed.
If you find this step difficult, remember the concept can be applied to any distance and speed. Just adjust the numbers you are working with, and the formula remains the same.

When solving travel time problems, you often need to convert your calculated time into different units. In this exercise, after finding the travel time in hours, it is required to convert this time into days to get a more practical sense of the duration.
Since there are 24 hours in a day, you can convert hours to days using the formula: \( t_{\text{days}} = \frac{t_{\text{hours}}}{24} \).
Applying this to our problem, we have 480 hours. So, \( t_{\text{days}} = \frac{480 \text{ hours}}{24} = 20 \text{ days} \).
This conversion helps contextualize the travel time into more understandable units, making it easier to comprehend how long the journey would actually take. Remember, whenever converting units, it is crucial to use the correct conversion factor to ensure accuracy in your calculations.

Solving travel time problems involves several basic mathematical operations including division, and sometimes multiplication. In the example given, we primarily use division.
First, we divide the distance by the speed to find the travel time in hours: \( \frac{384,000 \text{ km}}{800 \text{ km/h}} = 480 \text{ hours} \). Then, we convert the hours into days by another division: \( \frac{480 \text{ hours}}{24 \text{ hours/day}} = 20 \text{ days} \).
Understanding these basic mathematical operations is essential as they are the building blocks of solving more complex problems. Always ensure to perform operations carefully and double-check your work to avoid simple mistakes. Remember that practicing these calculations will make you more confident and efficient in solving similar problems.
