To calculate the speed in the mentioned interval, what we must do is calculate the average rate of change.

By definition, the average rate of change is given by:


AVR = (r(t2) - r(t1))/(t2 - t1)

Substituting values we have:


AVR = (4.2 - 2.8)/(0.084 - 0.051)

We rewrite:


AVR = 42.4 (Km)/(h)

Answer:

The average speed between 2.8 km and 4.2 km of the bus is:


AVR = 42.4 (Km)/(h)
