Question 223821
Convert 30 mi./hr. into ft./sec.



Step 1.  We note that 5280 ft = 1 mile.


Step 2.  We note that 1 hour = 60 minutes = 60 minutes * 60 seconds/minute = 3600 seconds.


Step 3.  Then (30 miles/hour) * (5280 ft/ mile) * (1 hour/3600 seconds) = 44 feet/second.  Note that the units of miles and hours cancel out in the numerator and denominator to get the desired feet/second.


Step 4.  ANSWER;  The solution is 44 feet/second from 30 miles/ hour.


I hope the above steps were helpful.
