I don't have the fill rates (how long each hose takes alone) from your problem. Can you give the times for the three hoses (e.g., hose A fills the pool in X hours, B in Y hours, C in Z hours)?

How to solve once you have them:
1. Compute each hose's rate in pools per hour: 1/X, 1/Y, 1/Z.
2. Add the rates: R = 1/X + 1/Y + 1/Z.
3. Time to fill = 1/R hours.
4. Add that duration to 10:00 a.m. Tuesday and convert any fractional hours to minutes. If it passes midnight, advance to Wednesday as needed.

If you post the three individual times I’ll compute the exact finish time and pick the correct choice.
