Raj and Amit start walking from the same place to reach the same mall but they choose different paths. Raj walks 6 m towards west and takes right turn and walks another 5 m. He then takes left turn and walks 4 m and at last he takes right turn and walks 3 m and reached the mall. Amit takes a left turn after walking 2 m in east and walks 8 m. After 8 m he turns left and walks straight and reaches the mall. What is the difference between the distances covered by them?
