Hey! ! !

Solution :-

☆ Let the speed of the train is Y km/h.



:- It takes 480Y hours

but if the speed were

8 km/h slower, it would take 480Y−8 hours.

we've got the equation:

●480Y−8 = 480Y +3


☆Multiple both sides of the equation by Y(Y−8). 


=> 480Y=480(Y−8)+3Y(Y−8)


=>Y2−8Y−1280=0

=> (−40)(Y+32)=0

:- Y=40,−32

, so the speed

is Y=40 km/h.



so the difference  is three hours
