# If a person has been riding a bike for 5 seconds and gone a distance of 30 meters (m), how fast is he or she going?

There really is no other details.

By the way, the correct answer below (which is all that can be done with the information given) is the average velocity, which depends only on where you start, where you finish (30 m away) and the time it takes to get there.  The person may or may not (probably was not) going this velocity the whole way, but it averaged out to this over the entire 30 m.  If we had more information, we could try to calculate the instantaneous velocity at some moment or other during the 30-m trip.
