Step 1: Understand the doubling rate. The amount of water in the tank doubles every hour. Step 2: Work backward from the full state. At 11:00h, the tank was full. Let the full volume be V. One hour before 11:00h, at 10:00h, the tank must have been half full, because it doubled to become full by 11:00h. So, at 10:00h, the volume was (V)/(2). Step 3: Continue working backward to find when it was a quarter full. One hour before 10:00h, at 09:00h, the tank must have been a quarter full, because it doubled to become half full by 10:00h. So, at 09:00h, the volume was (V)/(4). The tank was a quarter full at 09:00h. Comparing this with the given options: A 08:00h B 09:00h C 09:30h D 10:00h E 10:15h The correct option is B. The final answer is 09:00h. Send me the next one 📸
