c) I and II are examples of uniform motion
d) I and II are examples of non-uniform motion,
​

Answer 1

Answer:

 60 km

Explanation:

Speed of train while covering a distance of 240 \ km,    u=  

7

240

​

=34.3 km/h

Speed of train while covering a distance of 360 \ km,    u=  

6

360

​

=60 km/h

Thus speed of train changed and hence motion of train is an example of non-uniform motion.
