Question

pls show the procedure ​

Answer 1

• See first it is non uniform motion as first he travelled a distance in 1 min but the same distance again took him 1.5 min so here his motion is not constant or u can say non uniform ...................................Also average speed =total distance/total time=60/150=0.4 m /s

Answer 2

The boy covers equal distance in unequal interval of time. So,this motion is non-uniform.

Average Speed=Total distance/Total time

Time=2.5 minute

=150seconds

=30+30/150

=60/150

=0.4m/sec

The average speed is 0.4m/sec.
