Two trains leaving from two station 50 miles away from each other with constant speed of 60 miles per hour, approaches towards each other on different tracks. if length of each train is 1/6 mile. when they meet How much time they need to pass each other totally ?	Choose the correct answer:	A) 277	B) 87	C) 27	D) 10	E) 72
Explanation:   The trains are coming towards each other so their relative speed is 60 + 60= 
<gadget id="calculator">60 + 60</gadget>
<output>120</output>
120 mph   In this case the distance would be addition of lengths of trains.i.e 1/6 + 1/6= 1/3 m   T = dsds = 1/3 1/120 3/120 = 1/1360 h   Answer: 10
<result>D</result>
