The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Step-by-step explanation:
Given that,
The kitchen sink can fill in: 6 mins
The sink can drain in: 10 mins
We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,
Lets say, the full tank = 1
Filling rate =
Drainage rate =
Hence, the time to fill the tank would be:
(Multiply by LCM)
x = 15
Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
