Let the distance from o to pay =x
Time taken to cover x =18sec
We know, Average Speed = total distance /total time
i) distance =x, time =18
Hence, speed =x/18 - - - - - (1)
Also, average velocity = total displacement /total time
Hence, displacement =x and time =18
Velocity =x/18
ii) distance =2x
Time taken to cover x =18sec
We know, Average Speed = total distance /total time
i) distance =x, time =18
Hence, speed =x/18 - - - - - (1)
Also, average velocity = total displacement /total time
Hence, displacement =x and time =18
Velocity =x/18
ii) distance =2x
sorry forgot to write ii) part,here distance =2x and time =12+6=18 and displacement = 1/2x and time =18sec and rest apply the formula
