A man can row downstream at the rate of 24 Kmph and upstream at 7 Kmph. Find the man’s rate in still water and rate of current?

Answer»

15.5 Kmph, 8.5 Kmph



RATE of still water = 1/2 (down stream + UPSTREAM

= 1/2 (24 + 7) = 15.5 Kmph 

rate of CURRENT = 1/2 (down stream - upstream) 

= 1/2 (24 - 7)
= 1/2 (17

= 8.5 kmph
