If you assume the cable car is moving at a constant 60 miles per hour, about 4 and 1/2 months (138 days). The current fastest elevator in the world (in the Burj Khalifa) moves at 22 mph; taking that up would take you about a year. However, I'm told by a friend who used to work at Otis (the company that made the Burj Khalifa elevator) that the limiting factor on elevator speed is the comfort factor - there's a hard cap on the acceleration a standing person can comfortably take, and the course of the elevator is generally pretty short, so you don't have time to build up a decent head of speed. Presumably we can do a little better than that
