You will need
- - guide roads;
- - GoogleMaps;
- - GPS Navigator.
Before you can calculate the time of motion, determine the distance to the destination using the program Google Earth (Google maps). Using the ruler tool get directions, - get exact distance to the end point. This value is denoted by the letter s. In addition to GoogleMaps distance can be calculated by the map or the directory of roads.
Find out the average moving speed V. This value depends on how you plan to move. For example, the average speed of the car in the city - 40-60 km/h, outside town - 90 to 120 km/h If you walk, take the speed is 4-6 mph, or about 1.5 m/s.
When the path and speed is found, you can start calculating the time of movement. To do this, use the formula: t=s/v, where t is the desired time, and s and v - values found above.
It should be noted that before the division the dimension of the values necessary to result in the same measurement units. If the path you have in metres, then take the speed in meters per second. Conversely, if you know the path in kilometers, and speed take the kilometers per hour. In the first case, get the time in seconds and the second in hours. For example, find the time of motion, if you know the distance between the homes of two friends: s=2500 meters, while the car rides from one home to another through the lanes at speed v=36 km/h. To start, bring the speed in m/s: 36/3,6 = 10 m/s. the calculations according to the formula: t = s/v = 2500/10 = 250 seconds. As you can see, the journey time is slightly longer than 4 minutes.
As you can see, this method is rather complicated, and its accuracy is not very high, because the speed is taken "by eye". But if you have a GPS Navigator (as a separate device or built-in feature in the phone), it is possible to significantly improve the accuracy of the calculations.
Take a GPS device, set the map route. The program will immediately plot a route and display it on the map, denoting distance. Start to move on the route – on foot or by transport. Navigator will analyze the speed of your movement and automatically calculate the planned time path. At the end of your journey, navigate to aggregate information and view the exact time you spent on the movement.
To determine the time of movement, use a web calculator offered by many transport websites.
