1. Answer: 60 minutes
<u>Step-by-step explanation:</u>
Faucet A: 140 milliliters/min = 0.140 liters/min
Faucet B: 100 milliliters/min = 0.100 liters/min
Let x represent the amount of time
Faucet A + Faucet B = Full fish tank
0.140x + 0.100x = 14.4
0.240x = 14.4
x = 60

2. Answer: 40 minutes
<u>Step-by-step explanation:</u>
Quantity currently in tank: 4.8 liters
Water In: 150 milliliters/min = 0.150 liters/min
Water Out: 270 milliliters/min = 0.270 liters/min
Let x represent the amount of time
Qty in tank + In - Out = Empty fish tank
4.8 + 0.15x - 0.27x = 0
- 0.27x = -4.8
x = 40
