Which variable is most important to the following problem? At 9:00 a.m., a wind speed of 20 miles per hour was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p.m. After that, the wind speeds started to decrease. What was the top wind speed? A. the time of day the first measurement was made B. the miles-per-hour speed of the wind at its maximum point C. the number of hours it took for the wind speed to reach its minimum for the day

Answer:option-CStep-by-step explanation:We are given At 9:00 a.m., a wind speed of 20 miles per hour was recordedSo, initial wind speed =20 miles per hourEach measurement showed an increase in wind speed of 3 miles per hourThe strongest wind was recorded at 4:00 p.mso, top wind speed = initial wind speed + ( total number of hours between 9:00 am and  4:00 pm)*(change in wind speed)top wind speed = 20 mph+(16-9)*3[tex]=20+7\times 3[/tex][tex]=41[/tex] miles per hourSince, change in wind speed and initial wind speed are constant but the number of hours it took for the wind speed to reach its minimum for the day can be changedso, most important variables is the number of hours it took for the wind speed to reach its minimum for the day can be changed
