To calculate: Time the train will pass each other.

Answer to Problem 11P
There is no solution for this question as distance and velocity of one train is not given.
Explanation of Solution
Given information:
The train leaves at noon.
At 1:30 P.M another train leaves on parallel track opposite direction to the first train.
Speed of second train is 5 mile/hour faster than the first train.
Calculation:
In this question we have to solve at what time the train will pass each other, but this is impossible to solve because the distance between the two cities is not given. Secondly the velocity of the trainsare also not mentioned so we cannot assume or find the proper timing when the train will meet or pass each other without knowing the exact velocity of one of the trains. It is necessary to know the distance and velocity to find when the train will pass each other.
Thus, the data is inadequate in the question there is no solution to find at what time the train will pass each other.
