Answer 1

I): Speed=Distance/Time
=65-30 km/12:30-12:00 hrs
=35 km/00:30hrs
=3500 m/1800 s
=1.94m/s

ii): Average Speed=Total Distance/Total Time
=100000 m/7200 s
=13.88 m/s

iii):No because it has different speeds at
different time intervals

Answer 2

i). 70 km/hr ii). 50 km/hr III). No. Some half hours are slower and others are faster.  Uniform motion means speed never changes. Like from 11.30 to 12.00 it doesn't even move at all
