heya it's Aastha.......

◆let the speed of the train be X in time taken is Y.
according to question.

●1st condition .

(X + 10)(Y - 2 ) = xy ( distance= speed × time) .

x - 5y = -10.------1

●2nd condition.

(x-10)(y+3)=xy

3x -10y = 30.------2

◆by substitution method ....

from eq 1 .

x = -10+5y.

putting the value in eq. 2.

◆{y = 12 } &{ x = 50}.

thus,
the speed of train is 50 km per hour and the time is taken by train is 12 hour .

I hope it help you ✌️
