1]A man can row upstream at 11 kmph and downstream at 8 kmph.The speed of the stream is
a]3kmph b]9.5 kmph c]1.5 kmph d]6 kmph

speed of stream= (1/2) (11-8) = 3/2 = 1.5 kmph

2]A man can row upstream at 8 kmph and downstream at 13 kmph.The speed of the stream is
a]3kmph b]9.5 kmph c]2.5 kmph d]6 kmph

3]A man can row upstream at 6 kmph and downstream at 4 kmph.The speed of the stream is
a]1 kmph b]9.5 kmph c]1.5 kmph d]6 kmph

4]A man can row upstream at 14 kmph and downstream at 9 kmph.The rate of the current is
a]3kmph b]9.5 kmph c]2.5 kmph d]6 kmph

5]A man can row upstream at 11 kmph and downstream at 16 kmph.The speed of the stream is
a]3kmph b]9.5 kmph c]2.5 kmph d]6 kmph

6]A man can row upstream at 8 kmph and downstream at12 kmph.The rate of current is
a]2 kmph b]9.5 kmph c]1.5 kmph d]6 kmph
