Speed of a speed-boat when moving in the direction parallel to the direction of the current is 16 km/hr. Speed of the current is 3 km/hr. So the speed of the boat against the current will be (in km/hr)

A boat takes 2 hours more to travel 45 km upstream than to travel the same distance downstream. If the ratio of the speed of current to the speed of boat is 1 ∶ 4, then find the speed of the current.
A boat running downstream covers a distance of 8.4 km in 12 minutes. If the same boat at same speed and same distance require 15 minutes for upstream, then find the speed of the stream.
In one hour, a boat goes 11 km/hr along the stream and 5 km/hr against the stream. The speed of the boat in still water (in km/hr) is :
