Question

In 2011, 640,000 ha of the Amazon rainforest were cleared. Approximately how many hectares is that each hour?

Answer 1

Answer:

73.06 ha/hr

Explanation:

To calculates this, you will need to find out the number of hours in 2011.

There were 365 days in 2011.

Each day has 24 hours.

⇒ $365$ ×$24 = 8760$ hours

To calculate the hectares per hour, we divide the total number of hectares by the total number of hours.

$\frac{640000}{8760} = 73.059$

We rounded off this value to two decimal places:

73.06 hectares per hour of Amazon rainforest were cleared in 2011.

Answer 2

640000/ number of hours in a year
640000/ 8760
73.059

Hope this helps!
