1. **State the problem:** A ball rotates 6.6 times every 16 feet and moves at a speed of 53.32 km/h. We want to find how many times it rotates every minute. 2. **Convert speed to feet per minute:** - First, convert 53.32 km/h to feet per hour: $$53.32 \times 3280.84 = 174,927.5 \text{ feet/hour}$$ - Then convert feet per hour to feet per minute: $$\frac{174,927.5}{60} = 2,915.46 \text{ feet/minute}$$ 3. **Calculate rotations per minute:** - The ball rotates 6.6 times every 16 feet, so rotations per foot is: $$\frac{6.6}{16} = 0.4125 \text{ rotations/foot}$$ - Multiply rotations per foot by feet per minute: $$0.4125 \times 2,915.46 = 1,202.47 \text{ rotations/minute}$$ 4. **Final answer:** The ball rotates approximately **1,202.47 times every minute**.
