Let's break down the movement of the Snake Eyes Roller Coaster step by step to find out how far it needs to drop or climb to return to ground level.
- The coaster first climbs to 125 feet above ground level.
- It then drops 60 feet. After this drop, the height relative to ground level becomes: \[ 125 - 60 = 65 \text{ feet} \]
- Next, it climbs 135 feet. Now, its height becomes: \[ 65 + 135 = 200 \text{ feet} \]
Now, the coaster is at a height of 200 feet above ground level. To return to ground level, it needs to drop from 200 feet to 0 feet, which means it has to drop 200 feet.
Therefore, the answer is drop 200 feet.
