Boston is 4 hours ahead of Frankfurt and two hours behind India. X leaves Frankfurt at 06:00 pm on Friday and reaches Boston the next day. After waiting there for two hours, he leaves exactly at noon and reaches India at 01:00 am. On his return journey, he takes the same route as before, but halts at Boston for one hour less than his previous halt there. He then proceeds to Frankfurt.
