Problem Solving

If the train traveled for 25 hrs at 50 mph, it traveled a total of 1250 miles: (Rate)(Time) = Distance.

Let's calculate the distance of each of the answer choices to town W.

A. T --> V --> W = 600 + 750 = 1350

B. U --> V --> W = 500 + 750 = 1250

C. V --> W = 750

D. Y --> X --> W = 675 + 125 = 800

E. Z --> X --> W = 700 + 125 = 825

The correct answer is B.

The figure shows seven train stations and the distances, in miles, along with 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

OA B

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.
