Problem 4 Easy

A river features a waterfall with a height drop of approximately 30 meters and an average annual flow rate of 1010 cubic meters per second. What is the average annual flow rate in cubic meters per hour?

  • A.

    6.06\times {{10}^{4}}

  • B.

    3.136\times {{10}^{6}}

  • C.

    3.636\times {{10}^{6}}

  • D.

    36.36\times {{10}^{4}}

  • E.

    31.36\times {{10}^{6}}

Answer:C

The average annual flow rate of the waterfall is 1010 cubic meters per second. To express the flow rate in cubic meters per hour, we calculate: 1010 \times 60 \times 60 = 3636000 = 3.636 \times 10^6. Therefore, the answer is \boxed{\text{C}}.
