To solve this problem, let's consider the changes in height of the Snake Eyes Roller Coaster as positive and negative values on a number line.
Starting at ground level, the first climb is 125 feet. So, we move 125 units up on the number line.
Next, the coaster drops 60 feet. Thus, we move 60 units down on the number line.
Now, we have climbed back up 135 feet. Therefore, we move 135 units up on the number line.
To determine how far the coaster needs to drop or climb to be back at ground level, we have to add up the changes in height:
125 - 60 + 135 = 200
Therefore, the coaster needs to climb or drop 200 feet to be back at ground level.
The Snake Eyes Roller Coaster climbs 125 feet from ground level then drops 60 feet before climbing another 135 feet. How far does the coaster need to drop or climb to be back at ground level? (Hint: Draw a picture or use a number line
