Answer:
To solve this problem, you will need to find the circumference of the ferris wheel. You can do this by multiplying the diameter of the ferris wheel by π. The circumference of the ferris wheel will be approximately 205 feet. Next, you need to convert 450 yards to feet. There are 3 feet in a yard, so 450 yards is equal to 4503=<<4503=1350>>1350 feet. Now that you have the distance that Jack travels in feet, you can divide it by the circumference of the ferris wheel to find the number of complete revolutions he makes. This is equal to 1350/205=6.59, which means that Jack makes approximately 7 complete revolutions on the ferris wheel.
