A skier starts at an altitude of 2,500 feet. She descends going 4.5 feet per second. She stops to take a rest at an altitude of 2,430.25 feet. Which equations could be used to solve for how many seconds have passed before she stops to take a break? Select all that apply. A: 2,500 + 4.5s =2,430.25
B:2,500 - 4.5s =2,430.25
C:2,430 +4.5s =2,500
D:2,430 - 4.5s = 2,500
