the moaning carverns in california are 410 feet deep. A rappeller descends by rope 165 feet into the main carvern. How much deeper can the rappeller go into the carvern?
The total distance is 410ft. The rappeller has gone 165 ft so far. How many feet are left?

Mostly, it depends on how long his rope is ! If he goes past the end of his rope, he can go unexpectedly to the bottom!
