Question 223821: Convert 30 mi./hr. into ft./sec.
Answer by drj(1380)   (Show Source):
You can put this solution on YOUR website! 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.
