Question

On average, 35 million gallons of water flow over Niagara Falls every minute. How many mL of water flow over Niagara Falls in 12 hours on average?

a) 98.4 mL
b) 289.6 mL
c) 152.7 mL
d) 9.5 x 10ˆ13 mL

Answer 1

To find the flow rate of water over Niagara Falls in mL, we convert the given flow rate from gallons per minute to mL per minute using conversion factors. Then, we multiply this by 720 to find the flow rate in mL per 12 hours. The answer is 9.5 x 10¹³ mL.

Step-by-step explanation:

To find the flow rate of water over Niagara Falls in mL, we need to convert the given flow rate from gallons per minute to mL per minute. There are 3.78541 L in a gallon and 1000 mL in a liter, so we can use these conversion factors to find the flow rate in mL per minute. Then, we can multiply this by 720 to find the flow rate in mL per 12 hours.

Flow rate in mL per minute = 35 million gallons/minute * 3.78541 L/gallon * 1000 mL/L

Flow rate in mL per 12 hours = Flow rate in mL per minute * 720 minutes/12 hours

Calculating this, we get:

Flow rate in mL per 12 hours = 35 million gallons/minute * 3.78541 L/gallon * 1000 mL/L * 720 minutes/12 hours

Flow rate in mL per 12 hours = 35 million gallons * 3.78541 L/gallon * 1000 mL/L * 720 minutes/12 hours

Flow rate in mL per 12 hours = 12,780,600,000,000 mL

Therefore, the answer is (d) 9.5 x 10¹³ mL.
