Question

The underwater Terror toller-coaster tide takes passengers up to a 123 feet above ground. It then quickly drops the riders 154 feet into a underwater passageway. Next, the coaster immediately takes everyone straight up again 187 feet before it drops 175 feet into the second underwater passageway. What is the elevation of the 2nd underwater passageway relative to the ground? Please show your work.

Answer 1

up (+) 123 187

down (-) -154 -175

(123 + 187) - (154 + 175)

= 310 - 329

= -19

Answer: 19 feet below ground
