Two trains are moving in opposite directions at 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is? Choose the correct choice:	A) 76 sec	B) 88 sec	C) 48 sec	D) 44 sec	E) 33 sec
Relative speed = 60 + 90=

<output>150</output>
150 km/hr.= 150 * 5/18 = 125/3 m/sec.   Distance covered = 1.10 + 0.9= 
<gadget id="calculator">1.10 + 0.9</gadget>
<output>2</output>
2 km= 2000 m.   Required time = 2000 * 3/125= 
<gadget id="calculator">2000 * 3/125</gadget>
<output>48</output>
48 sec.   Answer: 48 sec
