Answer» c) is the right answer of the following c is the correct option c option is right answer Let total displacement be 3x and it's 1/3rd part is x, x and x average velocity = total displacement /total time ER. RAVI KUMAR ROY For T1(time ) =displacement/time =x/2sec T2 = x/3 sec T3 = x/6 sec Total time = x/2+x/3+x/6 =6x/x =X(total time) Now,average velocity = 3x/x= 3 m/s ANS... c is the correct answer c is the correct answer

Answer»

c) is the right answer of the following

c is the correct option

c option is right answer

Let total displacement be 3x and it's 1/3rd part is x, x and x

average velocity = total displacement /total time

ER. RAVI KUMAR ROY

For T1(time ) =displacement/time =x/2sec

T2 = x/3 sec

T3 = x/6 sec

Total time = x/2+x/3+x/6

=6x/x

=X(total time)

Now,average velocity = 3x/x= 3 m/s ANS...

c is the correct answer
