A) 40 B) 45 C) 48 D) 51 E) 36
Relative speed = 45 + 30=

<output>75</output>
75 km/hr.   75 * 5/18= 125/6 m/sec.   Distance covered = 375 + 375= 
<gadget id="calculator">375 + 375</gadget>
<output>750</output>
750 m.   Required time= 750 * 6/125= 
<gadget id="calculator">750 * 6/125</gadget>
<output>36</output>
36 sec.   Answer: Option 36
