Question

Water flows through a pipe at a rate of 2700 liters per month. Express this rate of flow in milliliters per minute.

a) 45 mL/min

b) 90 mL/min

c) 135 mL/min

d) 180 mL/min

Answer 1

The answer "b) 90 mL/min"

Step-by-step explanation:

1L = 1000 milliliters

1 month = 30 days

1 day = 24 hours

1 hour = 60 minutes

Daily flow rate = Monthly flow rate / Number of days in a month

Monthly flow rate = 2700 liters

1 month = 30 days

Daily flow rate = 2700 liters / 30 days = 90 liters per day

Flow rate in milliliters per minute = Daily flow rate * 1000 / 24 * 60

Flow rate in milliliters per minute = 90 * 1000 / 24 * 60 = 90 liters per day * 1000 milliliters per liter / 1440 minutes per day

Flow rate in milliliters per minute = 90,000 / 1440 mL per min

Flow rate in milliliters per minute ≈ 62.5 mL per min

the closer answer its b

Answer 2

The flow rate of water in milliliters per minute is 1.875 mL/min.

Step-by-step explanation:

To express the flow rate of water in milliliters per minute, we need to convert the given rate of 2700 liters per month into milliliters per minute. To do this, we can use unit conversion:

1 liter = 1000 milliliters

1 month = 30 days (approx.) = 30 * 24 * 60 minutes

Therefore, the flow rate is:

2700 liters/month * 1000 milliliters/liter * (1 month / (30 * 24 * 60) minutes) = 1.875 milliliters/minute

So, the correct answer is: a) 45 mL/min
