There is an elevator in a building that is 450 feet tall with 30 stories. Starting from the 20th floor, the elevator descends steadily toward the bottom floor, passing the 15th floor half a minute after its descent started. The graph below summarizes this information. Based on the graph, determine how fast the elevator travels and the time it would take to go from the 20th floor to the bottom of the building.

Bradley and kelly are out flying kites at a park one afternoon. a model of bradley and kelly's kites are shown below on the coordinate plane as kites brad and kely, respectively: kites adbr and kely are shown on a coordinate plane. the vertices of adbr are a is at 9, 1; d is at 1, 5; b is at 9, 9; and r i which statement is correct about the two kites? (1 point) they are similar because segment br to segment db is 1: 2 and segment ke to segment yk 1: 2. they are not similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 2. correct! they are not similar because segment br to segment db is 1: 2 and segment ke to segment yk is 1: 5. they are similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 5.
