Answer:
approximate speed would be 19 revolutions per minute.
Step-by-step explanation:
For model 5, blade length = 148 feet
Maximum blade tip speed = 200 miles per hour
tip of the blade travels per revolution = 0.18 mile
Number of revolutions per hour = [tex]\frac{200}{0.18}[/tex] = 1,111
To get speed per minute, divide by 1 minute ( 60 seconds ).
[tex]\frac{1,111}{60}[/tex] = 18.51 ≈ 19 revolutions per minute.
