A swimming pool holds 480,000 liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe

sweet-ann [11.9K]

The answer is 96 min, here is why:

x / 240 + x / 160 = 1
2x + 3x = 480 
5x = 480 
x = 96 min

(Drainage rate of first pipe = 480000/240 = 2000 l/min 
Drainage rate of second tube = 480000/160 = 3000 l/min 
Combined drainage rate = 5000 l/min 
Time to drain = 480000/5000 = 96 min. )
