Elevator #1 starts moving upward from a height of 28 feet at a rate of 8 feet per second. At the same time, elevator #2 starts moving downward from a height of 100 feet at a rate of 10 feet per second.
Part 1
Which two equations form a system that can be solved to find how many seconds (s) it will take for both elevators to reach the same height (h) in feet?
When the elevators reach the same height, how many feet high will they be? (Use the digits 0 – 9 to enter the number. Use a decimal point only if needed.)
