The speed of boat in still water is 20 km/hr. If it travels 26 km downstream and 14 km upstream in same time, what is the speed of the stream?	Choose the correct choice from the following answers:
A) 6  B) 7  C) 8  D) 9  E) 2
Explanation:   Let X be speed of stream   Speed of boat downstream = (20 + X )   Speed of boat upstream = (20 – X)   It is given that boat takes same time to travel 26 km downstream and 14 km upstream   [26/(20 +X)] = [14 / (20 – X)]   520 – 26 X = 280 + 14X   40X = 240   X = 6 km/hr   6NSWER: 6
