12 pm to 4 pm = 4 hours, 1 hour is 60 rotations, thus: 4*60=240 Rotations.
50. 225/4.5=50. Correct me if I’m wrong but I think that’s the way to do it!
Divide the scaled dimensions by 2, then multiply that by 7:
Length: 20 / 2 = 10. 10*7 = 70 feet.
Width: 10 / 2 = 5. 5 * 7 = 35 feet.
A) The pool is 70 feet long by 35 feet wide.
B) Area is length x width
Area = 70 * 35 = 2,450 square feet.
Cover cost 0.30 per square foot.
Total cost = 2,450 x 0.30 = $735
