Question

A roller coaster begins at 90 feet above ground level. Then it descends 105 feet. Which statement correctly finds the height of the coaster after the first descent?

90 + 105 = 195

90 - 105 = -195

105 - 90 = 15

90 - 105 = -15

Answer 1

The correct statement is 90 - 105 = -15. After the first descent, the height of the coaster would be 15 feet below ground level.
