7. Use dimensional analysis to convert 60miles per hour to feet per second. Remember that there are 5280 feet in 1 mile.
==============================================================================

Let m = miles, h = hour, f = feet, s = seconds
Then 60%28m%2Fh%295280%28f%2Fm%29+=+316800%28f%2Fh%29
316800%28f%2Fh%29%281%2F3600%29%28h%2Fs%29+=+88+%28f%2Fs%29
So, the 60 mph car is traveling 88 feet per second.
