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

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.
