Hi,

So the distance travelled is 50*25=1250 miles.
Going by the options, the distance between U and W sums up to 1250.
So B.

PS: I am not sure if you should post solutions to such questions before the OA is released, hence let me know if i need to remove this post. :grin:

Re-phrasing question stem:- What is the starting station point so that the train covers a distance of 50 mph*25h=1250miles reaching at W?
Option A:- Start point T, Distance covered=TV+VW=600+750=1350>1250(Eliminated)
Option B:- Start point U, Distance covered=UV+VW=500+750=1250 (Correct)

Distance(d)=time(t)*rate(r)
t=25 h
r= 50m/h
d=25*50=1250

We have to find on figure a station which is 1250 miles from station w

In My Opinion

We see the distance traveled was 50 x 25 = 1,250 miles. So we see that the train started at station U.

Given: The train traveled for 25 hours at a speed of 50 mph
Distance = (speed)(time) = (50 mph)(25 hours) = 1250 miles

So, we need to find a path to station W that is 1250 miles long.
If we travel from station U to V to W, the total distance is 1250 miles

So the train must have started its journey at station U.
