Q.  The speed of a boat in upstream is 60 kmph and the speed of the boat downstream is 80 kmph. Find the speed of the boat in still water and the speed of the stream?

a. 70, 10 kmph
b. 35, 27 kmph
c. 50, 60 kmph
d. 45, 55 kmph


ANSWER: See Answer
 
Speed of the boat in still water = (60+80)/2 = 70 kmph. Speed of the stream = (80-60)/2 = 10 kmph.
