![]() Make sure you convert the units so both their distance and time components match, or use our trip duration calculator above which will handle conversions automatically. Where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed. The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula: Our distance calculator will sometimes output the distance in more than one unit, for your convenience.Įxample: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? To find the miles covered, first, calculate 80 * 4 = 320 km, then convert km to miles by dividing by 1.6093 or by using our km to miles converter to get the answer: 198.84 miles. As usual, make sure that the time unit of the speed measure is the same as the time unit for the duration of the trip. The result will depend on the unit of the speed metric, for example if speed is given in mph, the result will be in miles, if it is given in km/h, the result will be in kilometers. 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. How to calculate the average speed of a car?.I mean the trip time calculator (at the moment its more like a trip time story teller xD) probably knows the speed limits on all roads in the game and if you could tell the trip time calculator "I will always drive 5 mph slower than the actual speed limit on a road" then it should be rather easy to make a good calculation and then the navigator would also be able to show you the fastest route to your destination (right now the navigator will always chose the shortest route if you want the fastest route, but the shortest route isn't always also the fastest route). If you drive in California the difference between the calculated time and the real time is very small (maybe 30 minutes or so), but if you drive in Utah then the difference can already be several hours and if we some day will be able to make a coast to coast trip then the difference will be DAYS! If i remember right its something between 46 and 47 mph). Lets say the trip time calculator tells you that you will arrive at 10 am and you drive with 65 mph then you will very soon see that the trip calculator has changed the time of arrival maybe to 9:30 am and a while later then maybe 9:20 am and so on and if you pause the game (look at the map for example) and then do the math (remaining distance divided by the "needed" time) you will always get the result 47 mph (or 46 mph. ![]() If you are 47 miles away from your destination the trip time calculator tells you that you will need exactly 1 hour to arrive there, no matter if you drive with 55 mph on a small road or with 80 mph on a interstate at that time. It doesn't matter what the speed limits are.
