Question

Greg is in a bike race. At mile marker four (out of ten), his speed was measured at 13.5 mph.

Answer 1

It is the instantaneous speed of the bike rider.

Explanation:

At the mile marker, the measured speed gives the instantaneous speed of the bike rider.

The instantaneous speed is speed measured at a precise or instance of time.

 Speed is the rate of change of distance with time. It is a scalar quantity that only shows magnitude with no reference to direction.

  Velocity is the displacement divided by time. It has both magnitude and directions.

Average speed is measured over a period of time as the distance increases from the starting point.

From this, we can see that 13.5mph is the instantaneous speed of the bike rider.
