Speed of a boat in standing water is 14 kmph and the speed of the stream is 1.2 kmph. A man rows to a place at a distance of 4864 km and comes back to the starting point. The total time taken by him is:  Select:	A) 600	B) 500	C) 700	D) 900	E) 800
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>
