Arh! Good question.
The units for V are determined by what units are used for D and T. So if you do 20/0.25 you have the velocity in ft / s.
To get an answer in mph you'll have to do the conversions.
20 ft converts to 20/(3 x 1760) miles and 0.25 s converts to 0.25/3600 hours.

Very good. Not too bad. Interesting question.

]]>speed = distance / time

At a certain instant, the speedometer of an automobile
reads V mi/h. During the next 1/4 s the automobile travels 20 ft.
Estimate V from this information.
Distance = 20 feet
Time = (1/4)s
Is the formula V = 20/(1/4)s miles per hour?
