Answer 1

Answer: Your welcome!

Explanation:

The incorrect ratio is 3 ft : 1 yd, as this ratio should be written as 3 ft : 1 yd. The correct ratio would be 1 yd : 3 ft, as there are 3 feet in one yard. Therefore, in order to convert Peyton's speed from yards per second to miles per hour, we need to multiply by 1 yd/3 ft and then multiply by 60 min/1 hr and then divide by 5280 ft/1 mi.
