Train C and D, 455 miles apart, are traveling toward each other at constant rates and in the same time zone. If train C left at 4 pm traveling at a speed of 60 miles per hour, and train D left at 5:45 pm and traveling at 45 miles per hour, then at what time would they pass each other?	Choose the correct option:
A) 9:05 pm B) 9:06 pm C) 9:07 pm D) 9:08 pm E) 9:09 pm
First, since C has a headstart then in that 1hr45min or 1.75hrs he travels 105 miles   Then remaining distance to be traveled will be   455 - 105= 
<gadget id="calculator">  455 - 105</gadget>
<output>350</output>
350 miles   Now, using relative rates (105)(t)= 350   This gives 10/3 hours   Now 5.45pm + 10/3 hours gives us 9.05pm   Hence answer is 9:05 pm
