Stations X and Y are connected by two separate, straight, parallel rail lines that are 250 miles long. Train P and train Q simultaneously left Station X and Station Y, respectively, and each train traveled to the other's point of departure. The two trains passed each other after traveling for 2 hours. When the two trains passed, which train was nearer to its destination?
(1) At the time when the two trains passed, train P had averaged a speed of 70 miles per hour.
(2) Train Q averaged a speed of 55 miles per hour for the entire trip.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
Distance = 250 miles
Passed each other after travelling for 2 hours
Statement 1 (At the time when the two trains passed, train P had averaged a speed of 70 miles per hour.)
Train P
Distance = 250 miles
Rate = 70 m/hr
Time = 2 hours
Distance already covered by train P = 140 miles
Distance covered by train by train Q = 110 miles
Therefore statement 1 should be sufficient.
Similary statement 2 is sufficient as the speed of Train Q is given when 2 trains pass each other.
Answer D.
