    Answer: (2) 50 min.
    Explanation:-
    Th speed of a man = 10 km/hr
    Time taken by the man to cover 5 km = 5/10 = 1/2 hr. or 30 min.
    He takes rest for 5 min. on every 1 km.
    If he covers 5 km  then, he takes rest for four times,
    Therefore,
    He takes total time for rest = 5 x 4 = 20 min
    Thus, taken time by a man to cover 5 km  = 20 + 30 = 50 min.
    Hence, the answer is (2) 50 min.
