A boat has a speed of 14kmph in standing water. The stream has a speed of 1.2kmph. What time does the boat take to go to a distance of 4864 km and come back? (hours)  Choose one.
A) 700	B) 378	C) 2696	D) 1207	E) 1712
Explanation:   A boat travels at the speed of 14 km/hr in still water.   =&gt; Speed of stream = 1.2 kmph   =&gt; Speed of boat downstream becomes 14 + 1.2= 
<gadget id="calculator">14 + 1.2</gadget>
<output>15.2</output>
15.2 kmph=&gt; Speed of boat upstream becomes 14 - 1.2= 
<gadget id="calculator">14 - 1.2</gadget>
<output>12.8</output>
12.8 kmph   Total time taken in the journey= Journey downstream + Journey upstream   Therefore, 4864(1/12.8 + 1/15.2) = 700 hours   700NSWER: 700
