a man can row at 5 kmph in still water. if the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?
divide(multiply(subtract(5, 1), const_3), 5)
"explanation : speed in still water = 5 kmph speed of the current = 1 kmph speed downstream = ( 5 + 1 ) = 6 kmph speed upstream = ( 5 - 1 ) = 4 kmph let the requited distance be x km total time taken = 1 hour = > x / 6 + x / 4 = 1 = > 2 x + 3 x = 12 = > 5 x = 12 = > x = 2.4 km . answer : option c"
