A blind person af

Answer :

Let the blind man starts from origin O and walk in + X direction till A and then take a left turn to move in + Y direction till B



X direction


No. of steps taken = 10


1 step = 80 cm


10 steps = 800 cm


1m = 100 cm


So, 10 steps = 8 m


Hence, x = OA = 8m


y direction


No. of steps taken = 40


1 step = 80 cm


10 steps = 3200 cm


1m = 100 cm


So, 10 steps = 32 m


Hence, y = AB = 32 m


Net Displacement = OB



Hence,
