Comprehension Passage
Directions: The following caselet shows the speed of three boats while traveling between two ports X and Y
Three boats A, B, and C traveling between ports X and Y which are 60 km apart. The ratio of the speed of the boats A and B in still water is 2 : 3. The ratio of speed of the boat A while traveling upstream to the speed of boat C while traveling downstream is 1 : 5. The speed of boat B while traveling downstream is twice of its speed while traveling upstream. The speed of the stream is 5 km/hr. While traveling port X to port Y the boats travel against the stream, and while traveling from port Y to port X they travel along with the stream.
While traveling from X to Y, a man travels on boat B, after spending one hour at port Y, he starts his return journey on the same boat. But in the midway, the boat stopped due to technical fault, so he switched to boat A after 30 minutes and returned to port X. Find the total time taken by for his journey.
