1ans. is (6^2+500^2)^(1/2)km i think.may e the ans is given wrong in the buk...it happens many times
1062) a possible way in which the book may have got 6.02 km .. is that
" The car moved 2 km towards east ,made a perpendicular left turn,ran for 500 m,made a perpendicular right turn ,ran for 4km & stopped."Find the displacement of the car.
instead of 500 km.
