⟩ An Engine length 1000 m moving at 10 m/s. A bird is flying from engine to end with x sec and coming back at 2x sec. Take total time of bird traveling as 187.5s. Find the to and fro speed of the bird?
distancetravelled by the bird=2000m
time taken=187.5 sec
=375/2 sec
speed is in the ratio of 1:2
dividing the time in the ratio of 1:2
time to=375/2(2/3)=125 sec
speed=distane/time=1000/125=8 m/sec
speed in thefro direction=16m/sec
