A man can row 6 km/hr in standing water and the speed of the current is 2 km/hr. It takes 3 hours more in upstream than to go downstream for the same distance. Find the distance to that place?

None

Speed upstream = 6-2 = 4 km/h Speed downstream = 6+2 = 8 km/h => x/4 = x/8 + 3 => x/4 = x+24/8 => 2x - x=24 => x = 24
