Question 70816
Draw the picture of the cable path.
To travel the first 15 horizontal distance the cable travels 15sqrt2 meters
because the cable car follows the hypotenuse of a right triangle with legs
equal to 15 meters.
To travel the last 15 horizontal distance the cable travels 15sqrt2 meters
for the same reason
--------------.
The horizontal part of the path is 1000-2(15)=970 meters
Total path =  970+2(15sqrt2) = 970+30sqrt2 = 970+42.4264 = 1012.4264 meters
------------
