A boat takes 2 hours to travel 8 km and back in a still water lake. With water velocity of 4 km/h, the time taken for going upstream of 8 km and coming back is given by:

Speed of boat relative to water =8 km/hSpeed downstream =12 km/hSpeed upstream =4 km/hTime taken with water flow =128+48hrs=2+32 hrs=160 mi
