Solve the problem.A water tank is being emptied such that the height y (in feet) of the water inside the tank decreases at a linear rate with time t measured in hours past 12:00 noon. If the height was 15 feet at 1:00 pm and 7.5 feet at 6:00 pm, find(a) the equation relating y to t, (b) the height at 12:00 noon, and (c) the total time required to empty the tank.
What will be an ideal response?
(a) y = -1.5t + 16.5
(b) 16.5 feet
(c) 11 hours
