Boat 'P' and Boat 'Q' are travelling in two different rivers called 'A' and 'B' respectively. Downstream speeds of boat 'P' and boat 'Q' are in the ratio of 6 : 5 respectively. The upstream speed of boat 'P' is 8 km/hr less than the downstream speed of boat 'Q'. If boat 'P' can cover 160 km in upstream in 5 hours and it is given that river 'B' flows 2 km/hr faster than river 'A' then find the time taken by boat 'Q' to cover the same distance in upstream?
