Two cars leave from the same place and travel along two straight roads. The two roads make an angle of 60° with each other at the point from which the cars begin their journey. The one car travels 60 km/h and the other at x km/h. If the cars are v1300 km apart after an hour, what is the speed of the other car? Apply the Law of Cosines to solve for r.
