Where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time. The formula for distance, if you know time (duration) and the average speed, is: If you want the result in km/h, you can convert from miles to km to get 788.58 km/h. If it was in meters and seconds, it will be in m/s (meters per second).Įxample: If you took a plane from New York to Los Angeles and the flight was 5 hours of air time, what was the speed of the plane, given that the flight path was 2450 miles? The answer is 2450 / 5 = 490 mph (miles per hour) average speed.

The resulting unit will depend on the units for both time and distance, so if your input was in miles and hours, the speed will be in mph. As noted above, make sure you convert the units appropriately first, or use our speed calculator which does that automatically.

Where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time. The formula for average speed, also called average velocity in physics and engineering, is: The unit of the result will depend on the units you input, but our speed calculator will conveniently display additional units where appropriate. If you have distance in kilometers, then speed should also be in km/h (kilometers per hour). For example, if you have speed in mph (miles per hour), time should also be in hours. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. You will need to convert the metrics to the same time and distance units, e.g. In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time.
DISTANCE TIME CALC HOW TO
How to calculate the average speed of a car?.This should give you a taster of C++11 and C++14. Std::tie(speed, formula) = calcSpeed(0.5, 0.2) // Assigns the first member of the pair to speed and the second member to formula. The C++ committee thought so as well and provided the following simpler method: double speed It's a little annoying to write all of this. You can then call calcSpeed like this: auto speed_and_formula = calcSpeed(0.5, 0.2) // Returns std::pairĪuto speed = speed_and_formula.first // This is the doubleĪuto formula = speed_and_cond // This is the string Result = (math.*p)(firstvalue, secondvalue, intform) // Double result = return value of chosen function **NON EXPLICIT (changes at runtime)** math is used as object to access public members P = &Math::calcSpeed // Redefines p to explicit function at runtime according to conditionsįirstParam = "distance" // Explanation stringsĬhosenCalcStr = "Speed" // Type in formula calculated #include ĭouble calcSpeed(double distance, double time, string& formula) // SPEED ~ Variable formula passed to the ufnction will be redefined I am a C++ beginner but I know quite a lot. The main reason I am asking, is to avoid bad practices and find better ways of doing what I'm doing. I am still looking to improve these parts as well. The current program calculates speed distance and time as well as showing all working which adds quite a lot of strings to store information. Could I add or improve functions so I could more easily add features like unit conversions?.I this the most efficient method and structure?.How might I improve to fit in with common best practices?.I am looking for suggestions to improve the efficiency of the program and how better to structure it - is my approach the best from a 'best practices', efficiency and OOP point of view.
DISTANCE TIME CALC CODE
This is a speed distance and time calculator - the comments should explain most of the odd looking code if there is any.
