Answer:
510 m
Explanation:
If a windbreak can reduce the speed of wind for distances up to 30 times the height of the trees, how far would these trees reduce the wind speed?
47 m
51 m
470 m
510 m
I will make the following assumption:
The average height of the trees =17m
since the preamble says that a wind break can reduce the speed of wind for distances up to 30 times the height of the trees
therefore, 30 *17
510m
Winbreaks are used for afforestation, redirecting wind movements, cattle ranch barrier etc.
