A miner descended 1100 feet into a mine. While in the mine, he then rose 950 feet and then descended 450 feet. What was the miner's net gain or loss in altitude?

Respuesta :

-600 feet because you do -1100+950-450
Total Rise or Drop = -1400 + 800 - 450 
Total Rise or Drop = -1050 

So, the total drop is 1050 feet
