Train G and H, 455 miles apart, are traveling toward each other at constant rates and in the same time zone. If train G left at 4 pm traveling at a speed of 60 miles per hour, and train H left at 5:45 pm and traveling at 45 miles per hour, then at what time would they pass each other?  Choose the most appropriate option
A) 9.05Am  B) 9.11pm  C) 8.05pm  D) 7.05pm  E) 9.05pm
First, since G 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 7.05pm
