20 meter
Distance covered by A in the race is 500 - 140 = 360 m
If his speed is 3x, then time taken by him = distance / speed (i.e 360/3x)
This is the time when A crosses the finish line.
Now let us see how far B has reached with his speed of 4 x in this time.
Distance covered by B = speed X time (i.e 4x X 360/3x)
which gives 480 m.
That means he is 20 m behind the finish line when A has already reached the finish liine.
Hope it help you
