Larger (smaller) velocity means
larger (smaller) acceleration.
Two cars are travelling down a road. At 12:15 pm the two drivers
of the cars look at their speedometers. The driver of one car reads
30 mph, the other driver reads 60 mph on their speedometer. Which car
has a greater acceleration? Explain your answer. If you are unable to
determine the answer, explain why you can't.
The answer cannot be determined, since
there is no information about whether (or how) the cars are speeding
up or slowing down.
