Answer 1

Let's summarize the divisibility rules: A number is divisible by 3 if the sum of its digits is divisible by 3. A number is divisible by 9 if the sum of its digits is divisible by 9. And a number is divisible by 6 if it is divisible by 2 (even number) and by 3.

${\huge{\underline{\underline{\text{\color {plum}{❥Aղʂաҽɾ}}}}}} {\huge{\text{\color{plum}{:- }}}}$

velocity of the person=vp=10m/s

velocity of the mirror= vm= -20m/s(since it

is in opposite direction)

velocity of the image=velocity of the

person-velocity of the mirror

v of image=10+20=30 m/s
