Let the speed of the train be 'x'km/h and the time taken by train to travel the given distance be 't' hours and the distance to travel be 'd'km.

We know that,

⇒Speed=\frac{Distance}{Time}

⇒x= \frac{d}{t}

∴d=xt.......(i)

Case 1

⇒(x+10)×(t−2)=d

⇒xt+10t−2x−20=d

⇒d+10t−2x−20=d

⇒−2x+10t=20...... (ii)

Case 2

⇒(x−10)×(t+3)=d

⇒xt−10t+3x−30=d

⇒d−10t+3x−30=d

⇒3x−10t=30......... (iii)

Adding equations (ii) and (iii), we get

⇒x=50

Substitute the value of x in (ii) we get

⇒(−2)×(50)+10t=20

⇒−100+10t=20

⇒10t=120

⇒t=12 hours

Substitute the value of t and x in equation (i), we get

Distance to travel =d=xt

⇒d=12×50=600Km

Hence, the distance covered by the train is 600km.

This is the best possible answer
