The figure shows seven train stations and the distances, in miles, along the railways that connect these stations. Beginning at one of the stations, a train takes 25 hours to travel directly to station W at an average rate of 50 miles per hour. At which of the stations did the train begin?

A. T
B. U
C. V
D. Y
E. Z

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.
