Question

Convert 50mL/sec to L/hr.
A) 180 L/hr
B) 90 L/hr
C) 360 L/hr
D) 45 L/hr

Answer 1

To convert 50 mL/sec to L/hr, divide 50 by 1000 to convert mL to L, resulting in 0.050 L/sec, and then multiply by 3600 to convert sec to hr, giving 180 L/hr as the correct answer.

Step-by-step explanation:

The task is to convert 50 mL/sec to L/hr. First, you need to convert milliliters to liters knowing that there are 1000 milliliters in a liter. So, you divide by 1000, moving the decimal point three places to the left, which transforms 50 mL into 0.050 L. Secondly, since we are converting from seconds to hours, and there are 3600 seconds in an hour, multiply 0.050 L/sec by 3600 sec/hr.

Here is the calculation: 0.050 L/sec × 3600 sec/hr = 180 L/hr. Therefore, the correct answer is A) 180 L/hr.
