average speed will b 70km/h and average velocity must b 0
average speed= total speed /2
60+80/2 =70

average velocity = displacement/time
here displacement is 0 bcz train come back to its starting point
therefore , average velocity is 0 km/h

cutiepieeee: ur answer is wrong the first part aberage speed is 68.57

cutiepieeee: can u plz tell me the process
