The balloon is 190 meters above the ground. It should fly over a hill with a height of 245 meters, if you drop a bag of sand, the balloon rises another 50 meters. Is it possible to fly over the hill after that?

1) Find out how many meters the balloon will rise when it drops a bag of sand.
190 + 50 = 240 m.
2) Let’s find out whether this distance from the ground is enough to overcome a hill with a height of 245 m.
Since 240 m is less than 245 m, the balloon cannot fly over the hill.
Answer: When you drop a sandbag, the balloon will not be able to fly over the hill.
