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.
