Explanation :   Speed downstream = (14 + 1.2)= 
<gadget id="calculator">(14 + 1.2)</gadget>
<output>15.2</output>
15.2 kmph   Speed upstream= (14 - 1.2)= 
<gadget id="calculator">(14 - 1.2)</gadget>
<output>12.8</output>
12.8 kmph   Total time taken= (4864/15.2) + (4864/12.8) = 320 + 380= 
<gadget id="calculator">320 + 380</gadget>
<output>700</output>
700 hours. 700 hoursnswer : Option 700 hours
