    Answer: (1) 610 m
    Explanation:-
    Distance covered in 1 min = 50 m
    Distance covered in 2 min= 90 m
    Thus, distance covered in 2nd min = 90 – 50 = 40 m
    Total distance covered in 3 min = 130 min
    Thus, distance traveled in 3rd min = 130 – 90 = 40 m

    By seeing this pattern, we can say that after 2nd minute he will cover 40m distance every minute.

    So, total distance covered in 15 min = Distance covered in 1st minute + distance 50 + 14 x 40
    = 50 + 560
    = 610 m
    Hence, the answer is (1) 610 m.
