A.) 120 - 2.5t = 1.5t
Adding 2.5t to both sides,
120 - 2.5t + 2.5t = 1.5t + 2.5t
120 = 4t
Dividing both sides by 4,
t = 120 ÷ 4
t = 30
B.) The solution represents the fact that at 30 seconds, James and Brianne are at the same height after 30 seconds of riding the elevator and running up the stairs respectively.
C.) Assuming it takes 1 second to complete 1 feet, and after 30 seconds, they have completed 30 feet, the height above the ground floor when they are at the same height at the same time will be 120 - 30 = 90feet.
