Correct option is B)
I : Speed of train while covering a distance of 240 \ km, u=7240=34.3km/h Speed of train while covering a distance of 360 \ km, u=6360=60km/h Thus speed of train changed and hence motion of train is an example of non-uniform motion. II : Speed of Gopi in the car race remains the same in first, second and third hour. Thus his motion is an example dof uniform motion. Correct answer is option B.
