-210-5x
Yes, assuming x = # of minutes.
depends what your expression is supposed to represent
Suppose you want to know the depth after t minutes
rate = 150/30 ft/min or 5 ft/min
so depth = 210 + 5t
Your answer is perfectly correct, since it also shows the position relative to the ocean floor,
mine shows the magnitude of that depth
