Convert the two given integers to binary strings. The distance using the curvature of the Earth is incorporated in the Haversine formula, which uses trigonometry to allow for the Earth’s curvature. If the car with greater velocity(in this case car B) is moving ahead, there is no chance of overtaking the other car A and hence the position-time graphs will not intersect, both the lines move far from each other as shown in the graphThe formula is a^2+b^2=c^2 (a squared + b squared = c squared), so you need to use +, not -. There are other formulas where the earth radus can be specified, and since GPS coordinatres are related to WGS84 erath modell, the WGS84 earth radius should be used. So if you want to calculate the closest edge, find the squared distances to each edge and select the smallest. lang. 0d)); double distanceY= (Math. 0d)); double distanceY= (Math. 2.
