the type of motion is non uniform motion.
As the speed does not remain constant throughout the journey the motion is non-uniform.
Total distance travelled in going and coming back,
d=30m+30m=60m
Total time taken in going and coming back
t=1min+1.5min=2.5min
=2.5×60s=150s
Average speed =
Total time of travel
Total distance travelled
=
150s
