a pool is filled with water in 6 hours at 100 m every hour. If 125 m could be filled every hour,the pool would be full at 11.00am.What was the latest possible time that the water could have started filling the pool
ht = 100m/h * 6h = 600 m.
ht. = 125m/hour * X hours = 600 m.
125x = 600
X = 4.8 hrs = 4hrs,48 min to fill pool.
T = 11:00 - 4:48
T = 10:60 - 4:48 = 6:12am=Starting time.
