The cable has to rise 2000 feet over a horizontal distance of 5000 feet. The cable would be the hypotenuse of a triangle with those sides, if it were a straight line. However, the cable will have to sag a lot due to its weight and that of the car.
This is not a well thought out problem.
The answer they probably are looking for is
sqrt[(2000)^2 + (5000)^2]
