Question: A river\'s flow rate is measured at 200 cubic meters per second. How much water flows through the river in one hour? (2020)

Options:

Correct Answer: 1,440,000 m³

Exam Year: 2020

Solution:

Water flow in one hour = Flow rate × Time = 200 m³/s × 3600 s = 720,000 m³.

A river's flow rate is measured at 200 cubic meters per second. How much water flows through the river in one hour? (2020)

A river's flow rate is measured at 200 cubic meters per second. How much water flows through the river in one hour? (2020)

Step 1: Understand the flow rate of the river, which is 200 cubic meters per second (m³/s).
Step 2: Determine how many seconds are in one hour. There are 60 seconds in a minute and 60 minutes in an hour, so: 60 seconds/minute × 60 minutes/hour = 3600 seconds.
Step 3: Multiply the flow rate by the total number of seconds in one hour to find the total water flow: 200 m³/s × 3600 s.
Step 4: Calculate the result: 200 × 3600 = 720,000 cubic meters (m³).
Step 5: Conclude that 720,000 m³ of water flows through the river in one hour.
