Different modes of transportation have varying speeds due to factors such as traffic, road conditions, and the capabilities of the vehicle. For example, the average walking speed for a human is approximately 3-4 miles per hour, while the average running speed can range from 5-10 miles per hour. Bicycles typically travel at an average speed of 10-15 miles per hour, while cars can go anywhere from 30-70 miles per hour depending on the road conditions and speed limits.
B. Calculating distance based on time and average speed
To calculate distance using this method, you will need to know the travel speed of the mode of transportation you are using and the time taken to travel. The formula for calculating distance is:
Distance = Speed × Time
For example, if you traveled in a car at an average speed of 60 miles per hour for 2 hours, the distance traveled would be:
Distance = 60 miles per hour × 2 hours = 120 miles
This method is particularly useful for measuring distance when you have a reliable estimate of the average speed and the time taken to travel. It is commonly used in road trips, hiking, and running activities where you have control over your travel speed and can track the time taken.
However, it is important to note that this method may not be accurate in situations where the speed is not consistent or there are external factors that can significantly affect the travel speed, such as heavy traffic or adverse weather conditions.
It is recommended to cross-reference and combine this method with other methods mentioned earlier to ensure accuracy in distance calculations.

Method 6: Using sound propagation speed
A. Basic explanation of how sound travels
In this section, we will explore the concept of using sound propagation speed to calculate distance. Sound travels through mediums such as air, water, and solids in the form of waves. The speed at which sound travels depends on the properties of the medium. For example, sound travels faster in solids compared to air.
B. Experimenting with time lapse of sound to determine distance
To calculate distance using sound propagation speed, you can conduct a simple experiment. Start by standing at a known distance from a stationary object. Clap your hands or make a loud noise and note the time it takes for the sound to reach the object and return to your ears as an echo.
Using the formula distance = speed × time, you can rearrange the formula to solve for distance. Divide the time it took for the sound to travel by 2 since it traveled to the object and back.
For example, if the time elapsed is 2 seconds, and the speed of sound in air is approximately 343 meters per second, the calculation would be as follows:
Distance = (343 m/s × 2 s) / 2 = 343 meters
C. Advantages and limitations of using sound propagation speed

A. Understanding the concept of shadow length and sun angles
In this section, we will explore another method to calculate distance without relying on time. By leveraging the concept of shadow length and sun angles, we can estimate distances with reasonable accuracy. The basic principle behind this method is that the length of an object’s shadow can be used to determine the length of the object itself, provided we know the angle of the sun.
To understand this concept, it is important to grasp the relationship between the position of the sun and the length of shadows. When the sun is directly overhead, the length of an object’s shadow is at its shortest. As the angle of the sun decreases, the shadow length increases. By measuring the length of a shadow at a specific time, we can deduce the height or length of the object casting the shadow.
B. Calculation process using time of day and shadow length
To calculate distance using shadows and sun angles, you will need a measuring tape or ruler, a level surface, and a clear understanding of the time of day. Start by placing the measuring tape or ruler vertically on the ground, ensuring it is level. Make note of the length of the shadow cast by the measuring tape or ruler.
Next, determine the angle of the sun by using a smartphone app or an online sun angle calculator. These tools provide the sun’s current angle based on your location and the time of day. Take note of the sun angle.
With the length of the shadow and the sun angle known, you can utilize basic trigonometry to calculate the height or length of an object. By applying the tangent function (tan) to the sun angle, you can determine the ratio between the length of the shadow and the object’s height or length. Solve for the unknown variable to find the distance.
It is important to note that this method works best on objects with known dimensions or proportions. For example, if you know the height of a lamppost or tree, you can use its shadow to estimate distance. However, if the object’s dimensions are unknown, it may be challenging to accurately calculate distance using this method.
Remember to account for any potential errors or limitations, such as uneven terrain or variations in shadow length due to nearby objects. Cross-referencing this method with other techniques, such as using landmarks and paces or GPS coordinates, can help improve the accuracy of your distance calculations.
By employing the shadow length and sun angles method, you can add another tool to your distance measurement repertoire, broadening your ability to calculate distances without relying solely on time.
