Its (a) Lucy, but here is a trick you can use if you get stumped in an exam with stuff like this. Its called "dimensional analysis" (swell name, good for cocktail parties) but it works like this. What are the "units" of the answer? You wanted velocity so maybe it is miles per hour. Or, better miles/hour. So, whatever you do, you must have something in miles and divide it by something in hours to have an answer that is in miles/hour. Just get the equation so that the dimensions will work out and it will be correct.

Velocity is speed per unit time. Thus it's "a". A car goes 65 miles per hour, which is distance (65 miles) divided by time (one hour).

Did you mean "velocity"?
The answer is a. Remember miles per hour is velocity? that is distance divided by time.

a.distance divided by time because velocity is rate of change
