The speed of the wind is changing according to the function V(t)=−t2+30 , where t = time in minutes after 6:00 p. M. And V(t) = wind speed in miles per hour (mph). Which statement best describes the meaning of the equation V(20)−V(10)=−5 ? In a period of 5 minutes, the wind speed increased from 10 mph to 20 mph. The wind speed decreased by 5 mph between 6:10 p. M. And 6:20 p. M. The wind speed increased by 5 mph between 6:10 p. M. And 6:20 p. M. In a period of 5 minutes, the wind speed decreased from 20 mph to 10 mph.
