a)12.5m//s
b)The speed of the bus has decreased, because the distance is the same and it took longer time to travel between them.

Explanation:

a) v_(avg)=(Deltax)/(Deltat)

The distance is 25m and the time is 2s, thus, the average velocity is

v_(avg)=25/2=12.5m//s

b) The same distance is covered by a longer time, therefore the speed of the bus has decreased.
