The Speed of a boat in still water is 25 kmph. If it can travel 10 km upstream in 1 hr, What time it would take to travel the same distance downstream?  Choose the correct choice from the following answers.
A) 26 minutes	B) 23 minutes	C) 15 minutes	D) 19 minutes	E) 28 minutes
Speed of boat in still water = 25 km/hr   Speed upstream = 10⁄1 = 10 km/hr   Speed of the stream = (25-10)=

<output>15</output>
15 km/hr   Speed downstream= (25+15)= 
<gadget id="calculator">(25+15)</gadget>
<output>40</output>
40 km/hr   Time taken to travel 10 km downstream= 10/40 hours=(10×60)/40= 15 minutes   Answer is 15 minutes
