Total time travelled= $|90-54|+|54-57|+|57-40|+|40-20|+|20-80|+|80-120|+|120-150|+|150-45|+|45-180| =446$

enter image description here

Total time take = $|90-80|+|80-57|+|57-54|+|54-45|+|45-40|+|40-20|+|20-120|+|120-150|+|150-180| =230$

Total time take= $|90-120|+|120-150|+|150-180|+|180-200|+|200-0|+|0-20|+|20-40|+|40-45|+|45-54|+|54-57|+|57-80| =421$
