QUESTION ---- a man Walks for one night at a speed of 1 metre per second and then runs for 1 net at a speed of 3 metre per second along a straight track what is the average speed of the man

ANSWER
__________________________

Length of Night is same i.e. Time is Same
And let Length of Night be x

For first Night,

Speed = 1 m/sec
Distance = x m
Time = x sec

For second Night,

Speed = 3 m/sec
Distance = 3x m
Time = x sec
_____________________________

Total Time = x + x
Total Time = 2x

Total Distance = 3x + x
Total Distance = 4x

Average Speed = Total Distance / Total Time

Average Speed = 4x / 2x

Average Speed = 2 m/sec

__________________________

ANSWER = 2 m/sec
