Choose the correct choice from the following options:  A) 52 kmph  B) 58 kmph  C) 62 kmph  D) 65 kmph  E) 75 kmph
Relative speed = 280/9 m / sec = ((280/9)*(18/5))=

<output>112</output>
112 kmph.   Speed of goods train= (112 - 60)= 
<gadget id="calculator">(112 - 60)</gadget>
<output>52</output>
52 kmph.   52 kmphnswer : 52 kmph
<result>A</result>
