    A boat can travel 10.8 km downstream in 27 minutes and 9.6 km upstream in 32 minutes. What is the total time taken by the boat to travel 48 km upstream and the same distance downstream together?

    A)  3 hours 30 minutes        

    B)  4 hours 15 minutes        

    C)  4 hours 40 minutes

    D)       4 hours 25 minutes

    E)  None of these

    Correct Answer: C

    Solution :

    DN Speed \[=\frac{10.8}{27}\times 60=24km/hr\] UP Speed \[=\frac{9.6}{32}\times 60=18km/hr\] \[\therefore \] Reqd time \[=\frac{48}{24}+\frac{48}{18}\] \[=2+2\frac{2}{3}=4\frac{2}{3}hr\] = 4 hr 40 min
