A man rows to a place 48 km distant and come back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is: Select the correct option.
A) 1 km/hr	B) 2 km/hr	C) 1.5 km/hr	D) 2.5 km/hr	E) 3.5 km/hr
Explanation:   1 km/hrssume that he moves 4 km downstream in   x   x hours   Then, speed downstream   =   distance/time =4/xkm/hr   Hence, speed downstream   =4/x=4/(1/2)= 
<gadget id="calculator">4/(1/2)</gadget>
<output>8</output>
8km/hr   speed upstream= 3/x=3/(1/2)= 
<gadget id="calculator">3/(1/2)</gadget>
<output>6</output>
6km/hr   Hence, rate of the stream=1/2(8-6)=1km/hr   1 km/hrNSWER IS 1 km/hr
