Answer:
73.06 hectares of amazon rain-forest were cleared in an hour.
Explanation:
Consider the provided information.
It is given that in 2011, 640,000 hectares of the amazon rain-forest were cleared.
We need to find how many hectares is that an hour.
First calculate the number of hours in 1 year.
There were 365 days in 2011.
The number of hours in each day is 24.
Thus, the number of hours in a year is:
365×24=8760
We need to find how many hectares is that an hour.
Divide the number 640,000 with 8760 as shown:
640000/8760=73.059 hectares
Hence, 73.06 hectares of amazon rain-forest were cleared in an hour.
