A towboat is a boat designed for pushing barges or car floats. Towboats are characterized by a square bow with steel knees for pushing and powerful engines. They are most often seen on inland waterways and western rivers where they can push more than 50 large barges lashed together into a tow of varying shapes and sizes. Towboats that travel long distances (linehaul) include living quarters for the crew. Outside of the USA towboats are usually referred to as "push boats" or "pushers".

It is about 4 knots up river and 10 knots down river ...
usually four miles per hour since there is a speed limit on canals.
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
Average Speed is different from average speed becoz speed is particular while avera speed is the total distance divided from time
