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? Select the correct option.
A) 26 sec	B) 28 sec	C) 48 sec	D) 22 sec	E) 12 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=
