OpenStudy (quickstudent):

5,280

@sammixboo

sammixboo (sammixboo):

Right! so 5280ft/1mile will help you

OpenStudy (quickstudent):

OK. What about 60minutes/1hour?

OpenStudy (wolf1728):

92 miles/hour * 5,280 feet/mile * 1 hour/3,600 second = 134.9333... feet per second Notice how the miles and hours cancel each other?
