thanks
its my pleasure☺☺
but answer is not right
it's ok dear
u have to find the avg velocity. but in question the speed is given dear
here displacement=0
because it returns to its initial position
ohh
sorry

let certain distance=x m
hence avg spped. = total distance/total time
= 2x/{(x/50)+(x/40)}
=2/{(1/50)+(1/40)}
= 44.44kmph
avg velocity=0kmph
because returns to its initial position
displacement=0
hence velocity=0
