A train met with an accident 60km away from station A. It completed the remaining journey at 5/6th of the original speed and reached station B 1hr 12mins late. Had the accident taken place 60km further, it would have been only 1hr late. what was the original speed of the train?

a. 60 km/hr
b. 55 km/hr
c. 65 km/hr
d. 70 km/hr
e. 48 km/hr

Not sure if I am correct, but will try to attempt this.

Case 1: Train meets an accident 60 kms from A
A------60kms---------(Acc1)---------------------------------B =>train is 1hr 12 mins late
xkm/s 5/6x km/s

Case 2: Train meets an accident 120 kms from A.

A------60kms---------(Acc1)-----60kms------(Acc2)------------B =>train is 1hr late
xkm/s 5/6km/s

Comparing the 2 cases, we can see that there is a 12 minute difference when the accident site is moved by 60 kms.
So, covering these 60 kms at normal speed is 12 mins faster than at 5/6th normal speed.

Time taken to cover 60 kms at normal speed = 60/x
Time taken to cover at 5/6th the speed = 6*60/5x

60*6/5x - 60/x = 12/60

Solving this, x = 60km/hr.

So, I guess the answer is A.

Please share the OA.
Also the source of this qsn. It somehow dsnt seem to GMAT like!

One of those sums you could get lost in algebra;

Let the speeds be 5X and 6X,

Had the train travelled in 6X speed for 60 kms longer, it would reach 12 mins earlier, translates,

60/5X = 60/6X + 12/60 (Everything is km/hr)

X=10. Org speed = 6X = 60 A
