In 20 seconds, a roller coaster goes up a 100-meter hill, then down 72 meters, and then back up a 48-meter rise. What integer re
Finger [1]

The question is an illustration of arithmetic operations.

The integer that represents the vertical rise is 76

<em>Upward movements are represented with positive, while downward movements are represented with negative.</em>

<em />

So, the given parameters are:

Up = 100m

Down = -72m

Up= 48m

The vertical rise is:

Rise = Up_1 + Down + Up_2

So, we have:

Rise = 100m -72m +48m

Rise = 76m

Hence, the integer that represents the vertical rise is 76
