It depends on how long a distance you want to measure!

A distance-time graph is created by placing the distance on the vertical axis with the time placed on the horizontal axis. The values can then be plotted using distance traveled on different intervals.
Because visible light is emitted at a known frequency (a time) and then it is as simple as Speed = Distance / Time therefore Distance = Speed x Time.
to measure the average speed of a car for instince you must use the following formula SPEED= distance divided by time
The formula for calculating average speed is: Average speed = Total distance / Total time Where: Total distance is the total distance traveled in a certain amount of time. Total time is the total amount of time it takes to travel the total distance. For example, if you travel 100 miles in 2 hours, your average speed would be 50 miles per hour. Average speed = 100 miles / 2 hours = 50 miles per hour Average speed can be used to calculate the speed of a car, a bike, a person, or any other object that is moving. It can also be used to calculate the speed of a process, such as the speed at which a computer program is running. Here are some examples of how average speed can be used: A driver wants to know how long it will take to travel from one city to another. They can use the average speed of their car to calculate the travel time. A runner wants to know how fast they are running. They can use a stopwatch to measure their time over a certain distance, and then use the average speed formula to calculate their speed. A company wants to know how long it takes to produce a certain number of products. They can use the average speed of their production line to calculate the production time. Average speed is a simple but useful tool that can be used to measure the speed of objects and processes.
If you know any two of the following you can calculate the third: -Period of planet's revolution -Orbital Speed -Distance from sun
Velocity (distance in a particular direction) is speed over time. You should be able to use this formula to calculate how your distance changes with time.

To calculate work done on an object one needs to use the following equation; work = force x distance or W = F x d
no
I usually leave 5 to 6 seconds minimum following distance under those condition, and have had no accidents . . .
Scientists would use the Doppler Effect to calculate the distance to a Star which had the newly-discovered planet.
It is five seconds
Use a stopwatch.
Speed = Distrance / time
When planning a road trip, the ability to calculate distance between various locations is critical. You need to calculate mileage to determine fuel cost for your trip as well as to plan a reasonable itinerary for your travels. There are several different ways that you can calculate distance, but many people are making use of a distance calculator online. These mapping tools are generally available to you for free. Some provide you with advanced features that allow you to calculate distance for your whole trip with daily calculations for your distance traveled between legs of your trip. These tools are just one of many ways to calculate distance for your trip. You can also use mapping tools on your smart phone, use a mileage table on an atlas and more.
Increase your following distance. It will take you longer to stop. Slowing down is also a really good idea.
