Thank you for the opportunity to help you with your question!
The answe r is 4. 1 hr/60 min.
This ratio is incorrectly written. It should have been 60 min/ 1 hr. First no. Of yards covered per Second is calculated as 50 yd/5.5 sec.then this number is multiplied by 60 sec/ 1 min to get yd/min. Then to convert yd/min to yd/hr one needs to multiply by the ratio 60 min/1 hr and not 1hr/60 min.
Please let me know if you need any clarification. I'm always happy to answer your questions.
