You can put this solution on YOUR website!
26 miles/hour= ------feet/second
-----------
miles have to become feet ; hours have to become seconds
---------------
(26 miles/hour)(5280 feet/1 mile)(1 hour/3600 seconds)
Note: (5280feet/1 mile) and (1 hour/3600 seconds) are called conversion units.
-----------------------
Cancel "miles", "hour" to get:
[26*5280]/[3600]feet/second
= 38.133333 ft/sec
