Answer:
<em>The wind speed was 31 miles per hour when the experiment began.</em>
Step-by-step explanation:
<u>Linear Dependency</u>
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
