Speed is distance travelled in a given time, so speed = distance / time.

40mph = 40 miles / 1 hour

each mile has 1760 yards, each of 3 feet, so there are 3x1760 = 5280ft in each mile, so 40 miles = 40x5280ft.

Each hour has 60 minutes and each minutes has 60 seconds, so 1 hour = 60x60 = 3600 seconds

So 40mph = 40miles/1hour = 40x5280ft/3600secs = 58.67fts-1
