1 hour= 3,600 seconds and 1 mile=5,280 feet. Make a conjecture about how you would convert a speed of 15 miles per hour to feet per second. Then convert. Please help answer thx

Answer 1

5280 / 3600 = ?
Then the answer of that, multiply by 15.

Answer 2

I had a teacher that made me memorize this: 60 mph is 88fps. That has been a handy conversion in my life. In this case, 15mph is 1/4 of 60, so the answer is 88/4=22fps
